AB  - This study aimed to investigate the adsorption of As(V), phosphate, and textile dye Acid Green 25 (AG-25) on layered double hydroxides Mn-Fe_LDH and corresponding membranes (wCell/Mn-Fe_LDH). The wCell membrane, derived from waste tobacco boxes, was formed by cross-linking of epoxy and amino modified cellulose fibers with epoxy modified Mn-Fe_LDH and lysine as cross-linker. Structural and morphological analyses were conducted for Mn-Fe_LDH and wCell/Mn-Fe_LDH. The batch system explored pH, contact time, temperature, and initial concentration effects on wCell/Mn-Fe_LDH adsorption efficiency. Adsorption capacities of 82.71, 106.9, and 130.3 mg g−1 were achieved for As(V), phosphate, and AG-25, respectively, indicating effective anionic species removal. Kinetic analysis suggested intraparticle diffusion as the rate-limiting step. Thermodynamic parameters and ionic strength effects indicated a physisorption mechanism for AG-25 and surface complexation for As(V) and phosphate. Biodegradation experiments after five adsorption/desorption cycles revealed the membrane’s decomposition, with phosphate’s strong bonding releasing essential elements valuable for soil fertilization. Effluent wastewater treatment demonstrated low environmental impact through the formation of insoluble As(V) salts and photocatalytic dye degradation.

AB  - The lab-made ferrite-aluminium layered double oxide (Fe/Al LDO) nanoparticles were used as reinforcement in the production of copper matrix composite coatings via the electrodeposition route in this study. The Cu coatings electrodeposited galvanostatically without and with low concentrations of Fe/Al LDO nanoparticles were characterized by SEM (morphology), AFM (topography and roughness), XRD (phase composition and texture), Vickers microindentation (hardness), and the static sessile drop method (wettability). All Cu coatings were fine-grained and microcrystalline with a (220) preferred orientation, with a tendency to increase the grain size, the roughness, and this degree of the preferred orientation with increasing the coating thickness. The cross-section analysis of coatings electrodeposited with Fe/Al LDO nanoparticles showed their uniform distribution throughout the coating. Hardness analysis of Cu coatings performed by application of the Chicot-Lesage (C-L) composite hardness model showed that Fe/Al LDO nanoparticles added to the electrolyte caused a change of the composite system from “soft film on hard cathode” into “hard film on soft cathode” type, confirming the successful incorporation of the nanoparticles in the coatings. The increase in roughness had a crucial effect on the wettability of the coatings, causing a change from hydrophilic reinforcement-free coatings to hydrophobic coatings obtained with incorporated Fe/Al LDO nanoparticles.

AB  - Textile industry wastewater is a significant source of pollution, often containing hazardous organicdyes like Crystal Violet (CV). Photocatalytic degradation using semiconductor materials such astitanium dioxide (TiO2) presents a promising solution for wastewater treatment due to its effectivenessin breaking down organic pollutants under UV irradiation. This study investigates the efficiency ofTiO2 as a catalyst for the photodegradation of CV removed from textile wastewater. Experimentaltrials were conducted in a batch reactor under UV irradiation, with CV (20 ppm) and varyingconcentrations of TiO2 catalyst. Results revealed a significant reduction in CV concentration withincreasing catalyst dosage (to 0.1 g/L) and irradiation time. The optimal conditions for maximumdegradation efficiency were determined, highlighting the potential of TiO2 photocatalysis for textilewastewater treatment. Furthermore, the kinetics of CV degradation were analyzed to understand thereaction mechanism and rate. The degradation of the dye (20 ppm) was 98% for 95 min with 0.1 mg/LTiO2. This research contributes to developing sustainable and efficient methods for treating textilewastewater, addressing environmental concerns associated with dye pollution.

AB  - The increase in waste polymer recycling has helped in promoting sustainability, and together with the use of renewable raw materials, it has become a widespread concept with positive effects on both the economy and ecology. Accordingly, the aim of this study was the synthesis of “green” plasticizers, marked as LA/PG/PET/EG/LA, formed from waste poly(ethylene terephthalate) (PET) and bio-based platform chemicals propylene glycol (PG) and levulinic acid (LA). The structure of the obtained plasticizers was complex, as confirmed by results from nuclear magnetic resonance (NMR) and Fourier-transform infrared spectroscopy (FTIR) analysis. The LA/PG/PET/EG/LA plasticizers and waste poly(vinyl chloride) (PVC) were used in an optimized technology for PVC re-granulate production. The hardness of the PVC-based material with “green” plasticizers, in comparison to commercial plasticizer dioctyl terephthalate (DOTP), increased by 11.3%, while migration decreased. An improved material homogeneity and wettability of the fibers by the matrix were observed using SEM analysis of the material’s fracture surface, with a higher efficiency of intermolecular interactions leading to better mechanical performances of the newly designed materials. Thus, LA/PG/PET/EG/LA are unique materials with good compounding and plasticizing potential for PVC, as revealed by differential scanning calorimetry (DSC) and dynamic mechanical analysis (DMA). In that manner, the use of bio-renewable resources and recycled polymers will contribute to diminishing waste polymer generation, contributing to a lower carbon footprint.

AB  - Polymer composites based on unsaturated polyester resin (UPR) and reinforced with particles based on unmodified/modified
plant provenance biosilica particles were synthesized and characterized. An unsaturated polyester resin was obtained from
waste poly (ethylene terephthalate (PET). Biosilaca particles are made from rice husk biomass. The surface of the produced
silica particles was modified using three different silanes: 3-trimethoxysilylpropyl methacrylate (MEMO), trimethoxyvinylsilane (TMEVS), and 3-aminopropyltrimethoxysilane (APTMS). The microhardness test method was used to investigate
the mechanical properties of synthesized composite material with variations in dwell times and applied loads. Optimization of
composite microhardness value prediction in function of synthesized parameters (type of modification of silica particles) and
measurement parameters (applied loads and dwell times) was done using the method of response surface methodology (RSM)
regression analysis. The maximal microhardness values (0.459 GPa) were obtained of type modification of silica particles with
vinyl with 80% confidence for 120 experimental variables. This method can be used to choose the optimal dwell time and load
for comparison of measurements between different composite materials and to enable the choice of the material in terms of
optimization of the quality of reinforcement and quality of interphase determined by surface modification.

AB  - Polymer resins based on acrylates obtained from Bis-GMA (Bisphenol A glycide methacrylate), which is suitable for photopolymerization, are used in dentistry for various purposes due to the ease of application and the possibility to influence their properties by adding reinforcements of different shapes, crystal structure and chemical compositions. Reinforcement in the form of particles based on MgAlLDH (layered double hydroxide) deposited on silica obtained from rice husks on two substrates. A metal base and glass were used. The adhesive properties are important in order to see the possibility of using these materials in applications. In order to measure the adhesive properties of the material, the composite microhardness measurement method is used by applying different loads in order to evaluate the adhesion parameter that shows the effect of the coating on the substrate. It was compared to how a pure photopolymerizing acrylate matrix bonds with a chromium-based dental alloy substrate that is used in the production of different parts of dentures by bonding to a glass substrate. Then, it was compared how composite materials are bonded to both substrates. Adhesion was monitored through the change in wetting angle between the composites, and the results were compared with the results of microindentation. It was shown that the addition of composite particles increases the adhesive properties of the composite compared to the pure matrix and that better adhesion is achieved between the composite and the metal substrate than between the composite and the glass substrate.

AB  - Materials from green resources boast a low carbon footprint, forming the foundation of
 the circular economy approach in materials science. Thus, in this study, waste poly(ethylene
terephthalate) (PET) was subjected to depolymerization using propylene glycol (PG), and
subsequent polycondensation with bio-based maleic anhydride (MA) produced unsaturated
 polyester resin (b-UPR). Bio-derived acryloyl-modified Kraft lignin (KfL-A) served as a vinyl
 reactive filler in the b-UPR matrix to create b-UPR/KfL-A composites. The structural
characterization of KfL-A and b-UPR involved the use of FTIR and NMR techniques. The
 mechanical properties of the newly fabricated composites were assessed through tensile strength,
 Vickers microhardness, and dynamic mechanical tests. The addition of KfL-A to the rigid b-UPR
 matrix enhanced material flexibility, resulting in less stiff and hard materials while preserving
 composite toughness. For instance, incorporating 10 wt.% of KfL-A in b-UPR led to a 17%
 reduction in hardness, a 48% decrease in tensile strength, and a 20% reduction in toughness.
 Positive environmental impact was achieved by incorporation of 64 wt.% of renewable and
 recycled raw material. Analogously prepared b-UPR/KfL composites showed structural
 inhomogeneity and somewhat better mechanical properties. Transmission (TEM) and scanning
(SEM) electron microscopies revealed a suitable relationship between mechanical and structural
 properties of composites in relation to the extent of KfL-A addition. The UL94V flammability
 rating confirmed that flame resistance increased proportionally with the KfL-A addition. Once
 deposited in a landfill, these composites are expected to disintegrate more easily than PET, causing less harm to the environment and contributing to sustainability in the plastics cycle.

Various application techniques and the following substances were tested: stearic acid, shellac and zinc-hydroxide. Hydrophobicity was tested using the modified Cobb method, measuring the contact angle and drop retention time. The presence of hydrophobizing agents was confirmed by FTIR spectroscopy. It was found that the methods of applying the hydrophobizing agent, used in this work, give much better results with stearic acid, compared to shellac.

AB  - This study focuses on the removal of cation and cationic dye from wastewater by adsorption on a biobased adsorbent. Cellulose bio-based membrane, CMTA, was obtained by cross-linking of aminomodified cellulose fiber (CF-A) and tartaric acid (TA) using L-lysine as a cross-linker. The properties of the prepared membrane were examined through FTIR and SEM techniques, and pHpzc and porosity determination. The effect of pH, initial concentration, temperature, and contact time on the adsorption efficiency was studied in a batch system. Results from the adsorption study proved CMTA adsorbs of Crystal violet (CV) dye and Ni2+ cation ion with high adsorption capacities of 285.01 mg g-1 and 54.35 mg g-1, respectively, fitted to the Langmuir isotherm. The kinetic study and thermodynamic parameters determination indicate spontaneous and diffusion-controlled processes.

AB  - Thymus serpyllum L. (wild thyme) extracts were prepared using 1 g of plant material and three natural deep eutectic solvents (30 mL, malic acid+maltose, lactic acid+menthol, or citric acid+glycerol with 50% of water) in maceration (90 min). The extracts were characterized in terms of total polyphenol content (TPC), total protein content, extraction yield, zeta potential, conductivity, pH, density, surface tension, and viscosity. TPC was the highest in citric acid+glycerol extract (35.06±1.13 mg gallic acid equivalents (GAE)/g of plant material), whereas malic acid+maltose and lactic acid+menthol extracts possessed similar TPC (29.62±1.11 and 28.94±1.15 mg GAE/g, respectively). Total protein content amounted to 5.55±0.20 mg/g in citric acid+glycerol extract, while significantly lower values were determined in malic acid+maltose and lactic acid+menthol extracts (1.22±0.30 and 1.73±0.18 mg/g, respectively). The extraction yield was the highest for citric acid+glycerol extract, 1.57±0.11%, followed by malic acid+maltose and lactic acid+menthol extracts, 1.28±0.10 and 1.27±0.13%, respectively. Zeta potential (absolute value, as a predictor of potential application in water treatment) was low in all extracts (0.86±0.06 mV for citric acid+glycerol, -0.35±0.09 mV for lactic acid+menthol, and -0.17±0.05 mV for malic acid+maltose extract). The conductivity (as a predictor of antioxidant capacity) was in the range of 2.35±0.21 and 2.71±0.29 mS/cm (citric acid+glycerol and malic acid+maltose extracts) to 5.70±0.23 mS/cm (lactic acid+menthol extract). pH ranged from 1.44 in citric acid+glycerol extract to 1.78 and 1.85 in malic acid+maltose and lactic acid+menthol extracts. Density varied from 1.067±0.003 g/mL for lactic acid+menthol extract to 1.169±0.002 and 1.195±0.005 g/mL for citric acid+glycerol and malic acid+maltose extracts. Surface tension was the highest in citric acid+glycerol extract (38.0±0.4 mN/m), followed by malic acid+maltose and lactic acid+menthol extracts (31.5±0.4 and 25.9±0.1 mN/m, respectively). The viscosity of lactic acid+menthol extract was significantly lower (1.83±0.30 mPa•s) in comparison to malic acid+maltose and citric acid+glycerol extracts (6.64±0.15 and 7.84±0.10 mPa•s, respectively). The highest TPC, total proteins, and extraction yield were measured in citric acid+glycerol extract, while lactic acid+menthol extract possessed the highest conductivity and the lowest density, surface tension, and viscosity. Therefore, the constitution of natural deep eutectic solvent should be optimized depending on the future application of T. serpyllum extract.

AB  - The plants contain a large number of various compounds that exhibit significant antioxidant 
activity. Among them, polyphenols and flavonoids are the most studied compounds with different 
biological properties, including antioxidant activity. The functionalization of cotton fabric with natural compounds from plants results in the material with improved antioxidative properties. In this study, cotton fabrics treated with ethanol and water Thymus serpyllum L. (wild thyme) extracts were investigated in terms of antioxidant properties and chemical composition. In vitro antioxidant capacity of ethanol and water extracts, and the cotton fabric before and after functionalization was evaluated using 2,2-diphenyl-1-picrylhydrazyl (DPPH•), and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS•+) radicals scavenging capacity assays. FTIR and UV–Vis spectroscopy elucidated the structure of the cotton fabric, extracts, and functionalized cotton fabric. FTIR spectroscopy demonstrated that the structure of cellulose was dominated in cotton, and also proved the presence of a low percentage of protein, pectin, oil, fat, and wax, as well as, binding of compounds from the extract by cross-linking with long chains of structure cotton. In dry extracts, the presence of various chemical functional groups was confirmed. UV-Vis analysis identified the active components in T. serpyllum extracts. Namely, absorption values for both spectra (water and ethanol samples) at 215-253 nm, 263-384 nm, are specific for phenolic acids, and flavonoids. Also, one of the aims of the study was to investigate the influence of various extracts (water and ethanol samples) on the antioxidant activity of cotton fabric. All extracts demonstrated excellent antioxidant properties, more potent than the reference antioxidant (ascorbic acid) in both antioxidant assays (between 85-86% in DPPH and 94-96% in ABTS assays). Pure T. serpyllum water extract was the most potent in the DPPH assay (86%), while pure ethanolic extract was the most potent antioxidant in the ABTS assay (96%). The antioxidant capacity of raw cotton fabric was insufficient (4%). On the other hand, in the DPPH assay, samples of cotton fabric with extract showed moderate activity with scavenging activity of 48% and 45% for ethanol and water extracts, respectively. Additionally,
in the ABTS assay, the antioxidant activity of treated cotton fabric was 51% and 46% for ethanol 
and water extracts, respectively.

AB  - This paper presents sustainable technology for environmentally friendly composite production. Biobased unsaturated polyester resin (b-UPR), synthesized from waste polyethylene terephthalate (PET) glycosylate and renewable origin maleic anhydride (MAnh) and propylene glycol
(PG), was reinforced with unmodified and vinyl-modified biosilica nanoparticles obtained from
rice husk. The structural and morphological properties of the obtained particles, b-UPR, as well as
composites, were characterized by Fourier-transform infrared spectroscopy (FTIR), nuclear magnetic
resonance spectroscopy (NMR), scanning electron microscopy (SEM), and transmission electron
microscopy (TEM) techniques. The study of the influence of biosilica modification on the mechanical
properties of composites was supported by hardness modeling. Improvement of the tensile strength
of the b-UPR-based composite at 2.5 wt.% addition of biosilica modified with vinyl silane, named
“b-UPR/SiO2
-V” composite, has been achieved with 88% increase. The thermal aging process applied
to the b-UPR/SiO2
-V composite, which simulates use over the product’s lifetime, leads to the deterioration of composites that were used as fillers in commercial unsaturated polyester resin (c-UPR).
The grinded artificially aged b-UPR composites were used as filler in c-UPR for the production of a
table top layer with outstanding mechanical properties, i.e., impact resistance and microhardness, as
well as fire resistance rated in the V-0 category according to the UL-94 test. Developing sustainable
composites that are chemically synthesized from renewable sources is important from the aspect of
preserving the environment and existing resources as well as the extending their life cycle.

AB  - Acrylate polymers are used in several applications such as dentistry, medicine,
and industry. The modification of their properties using the reinforcement is
of key importance for the possible applications. Layered double hydroxides are
materials that are easily synthesized by several techniques giving the possibility to modulate the chemical composition and morphology of the reinforcement and they consist of a divalent and a trivalent anion hydroxide and the
layers can be exfoliated and thus provide a material interesting for composite
reinforcement. In this paper, Mn was used as a divalent and Al as a trivalent
cation. The obtained particles were used as reinforcement for the preparation
of composites in 1, 3, and 5 wt% quantities and prepared samples were compared to the matrix consisting of PMMA. Physical mechanical properties of the
sample having the best mechanical properties (with 3 wt% of MnAl-LDH
filers) exhibited 6.38% modulus of elasticity, 27% hardness, and 10% tensile
strength improved values compared to the clear PMMA matrix. Toughness
was lowered in this sort of composite compared to the pure matrix.

AB  - Nickel pollution of water induces several problems for the environment. The purpose of this paper was toinvestigate the adsorption of Ni2+ ions on fabricated biomembranes. The proposed adsorbent was preparedfrom epoxy and amino-functionalized waste cellulose fibers, able to participate in cross-linking with aminoacid lysine - wCell/Mn-Fe_LDH. The prepared material underwent preliminary structural characterizationby Fourier-transform infrared spectroscopy. In a batch system, the influence of pH, contact time,temperature, and initial concentration on adsorption efficiency was investigated. The effectiveness of themembrane was demonstrated by acceptable adsorption capacities of 40.49 mg g-1 obtained for Ni2+ at 45°C.The kinetic study, using the Weber-Morris model, indicates intraparticle diffusion as the rate limiting step.Adsorption mechanism physisorption was proposed based on thermodynamic behaviors. The outcomesdemonstrated that environmentally friendly sustainable technology has been successfully developed.

AB  - Worldwide pollution induces a negative impact on the complete environment. Modern societies are becomingmore involved in developing and implementing climate change adaptation policies as a result ofthe enormous hazards that climate change poses to human safety worldwide. One of the biggest problemsthat highly affects climate change is plastic pollution. Also, the utilization of a linear economy prevents theopportunity of solving mentioned problem. Hence, a major component of the strategy for tackling plasticpollution and trying to decrease global weather changes is an implementation of a circular economy. Plastichas to be reduced, reused, and recycled since its widespread consumption has put environmental protectionat risk. PET, also known as polyethylene terephthalate, is a prominent polymer material used forthe production of packaging, particularly plastic bottles. The majority of PET-based products are madeusing raw materials supplied from fossil fuels. However, methods based on biobased materials and recycling-modified products for obtaining novel products from waste PET have fewer greenhouse gas (GHG)emissions than the traditional method. Therefore, the subject of this paper is the innovative technology forthe fabrication of materials by PET recycling. Obtained monomer units - glycolysates were acquired by PETdepolymerization by inducing greener solutions. The resulting glycolysate was structurally modified withmaleic anhydride and finally with 2-octanol to obtain a novel plasticizer. The physicochemical characterizationof the obtained plasticizer, performed by infrared spectroscopy with Fourier transform (FTIR) andNMR spectroscopy, confirmed structural modifications. The mechanical characteristics of the final productwere tested after the plasticizers had been combined with bitumen at a range from 1 to 10 wt.% concentration.In addition, other PET recycling techniques will be presented and discussed. By comparing them,it will be determined which technique is most suitable for recycling with the smallest carbon footprint. Thesecond purpose of the research is to evaluate and contrast the financial and ecological implications of recyclingPET in comparison to other types of waste and renewable energy sources.

AB  - Cotton-based membranes, due to their exceptional biocompatibility and sustainability,have attracted considerable attention in various applications, especially in the field of bio andgreen technologies. This study investigates the biodegradation potential of cotton membranesmodified with TEMPO (2,2,6,6-tetramethylpiperidine-1-oxyl) radical and citric acid (CA),with the aim of improving their properties and facilitating environmentally friendly disposal.TEMPO radicals, in conjunction with the crosslinker citric acid, are incorporated into thecellulose structure through a novel modification process. The citric acid component acted as aplasticizer, increasing the amorphous parts of the cellulose and promoting enzymatic attack.The TEMPO radical, with its nitroxyl group, contributed to the oxidation of cellulose, furtherfacilitating biodegradation.The biodegradation aspect of these modified membranes was investigated incontrolled environmental conditions (Soil Burial test), simulating natural scenarios (humidity,influence of enzymes, and bacteria). Biodegradation parameters such as weight loss,structural changes, and degradation kinetics were examined during 90 days. Characterizationof the structure was performed using FTIR and SEM methods.Our findings suggest that cellulosic membranes possess complete (100%)biodegradability after 70 days compared to unmodified membranes. Obtained result shedlight on the potential of membranes modified in this way as sustainable and biodegradablealternatives in various applications. The results emphasize their ecological nature and abilityto reduce environmental stress. Such cellulose-based materials promise a much greener futurein biotechnology, healthcare, and environmental protection.

AB  - Styrene-butadiene (SBR) and acrylonitrile-butadiene (NBR) rubber blends with tetramethyl thiuram disulfide (TMTD) and tetramethyl thiuram monosulfide (TMTS) accelerators and environmentally friendly plasticizers, obtained from PET recycling and biobased resources (LA/PG/PET/EG/LA), were prepared. The mechanical properties of the obtained rubber products were tested and compared with those of commercial dioctyl terephthalate (DOTP). TMTS was prepared by simple and efficient one-pot synthesis from dimethylamine, carbon disulfide, potassium cyanide, and ammonium chloride as catalysts in recycled isopropanol/water azeotrope as solvent. In a comparative study, methoxide, ethoxide, iodide, and amide ions were also used. The two-step reaction mechanism of TMTS synthesis involves the oxidation of the amine salt of dimethyldithiocarbamic acid to TMTD by hydrogen peroxide and sulfur elimination from the TMTD disulfide bond. Potassium cyanide appears to be the most efficient nucleophile. The simplicity of operation, mild reaction conditions, solvent recycling, high yields, and applicability to the industrial level are the advantages of this process. Shore hardness, tensile strength, and compression test results of vulcanized blends before and after aging showed similar properties for both accelerators, while somewhat better results were obtained with LA/PG/PET/EG/LA plasticizer.

AB  - Oxidized cotton linters, TOCell, were used as an adsorbent or derived membrane there from by linterscross-linking with citric acid. The adsorption/desorption study of Pb2+, methylene blue (MB), and crystalviolet (CV) removal, was performed. Adsorption data fitting, obtained using the Langmuir model, gave116 mg g 1 (Pb2+), 179 mg g 1 (MB) and 482 mg g 1 (CV) at 25 ℃ for TOCell linters, while 101 mg g 1(Pb2+), 165 mg g 1 (MB) and 426 mg g 1 (CV) for TOCell membrane. After desorption dyes were subjectedto photocatalytic degradation while lead was transformed into stable lead phthalate (LP), and furtherused as filler in composites based on unsaturated polyester resins (UPR). UPR was synthesized fromwaste polyethylene terephthalate (PET). Structural characterization was performed using FTIR, SEM,and NMR methods. Composites loaded with acryloyl modified kraft lignin (A-KfL) and/or LP was testedfor tensile strength, Vickers microhardness, and fire resistance (UL-94 V method). The best mechanicaland fireproofing properties were obtained at 15 wt.% A-KfL and 40 wt.% Al(OH)3 addition. The resultsof the toxicity leaching test (TCLP) confirmed the environmentally safe stabilization of desorbed pollutantin the UPR matrix. Application of environmentally friendly membranes, susceptible to easy biodegradation, had low negative effects to the environment.

AB  - Population growth, the development of agriculture, industry, and mining, caused the creation of an increasing amount of  wastewater. Due to the discharge of wastewater, without prior treatment, the quality of water resources is impaired.  Polluting substances, such as pesticides, have a negative impact on human health and the environment. Heavy pollution  of both surface and underground water is one of the biggest problems associated with the use of pesticides. They reach  human organisms indirectly via agricultural products. Most pesticides are more or less toxic, some of them are highly  soluble in water. In recent years, special attention has been paid to the development of methods for the treatment of  wastewater contaminated with pesticide residues, in order to partially reduce or eliminate their further impact on humans,  plants, and the environment. Among many processes, the photocatalytic degradation process has proven to be a very  effective process for the removal of pesticides from wastewater. Photocatalytic degradation implies the breakdown of  various types of toxic organic substances into simpler molecules, such as ions, water, etc.  In this paper, the photocatalytic degradation of the pesticide mesotrione (MS) using ZnO photocatalyst is presented. The  degradation of the pesticide compound was studied using Shimadzu 1800 analytical UV-VIS spectroscopy. As a  replacement for UVC radiation, a solar-imitated irradiation Ultra Vitalux (UV) lamp (300W) was used. Degradation  kinetics follows pseudo-first order. After 240 minutes, the MS was completely degraded.

AB  - This paper presents the possibilities of making paper with increased water resistance as occupational therapy for people with developmental disabilities. Paper production using biodegradable additives was presented and their hydrophobicity was tested using the drop retention time method. It was found that papers containing an agent used for hydrophobization had a prolonged drop retention time. The efficiency of the functionalization of the paper structure and the hydrophobization agent was confirmed by FTIR-spectroscopy. The mechanical properties of all prepared samples were tested and it was determined that functionalization with rosin maleic anhydride sodium salt Na-(RMA) gives better results compared to sodium abietate (Na-Ab).
AB  - У статті представлені можливості виготовлення паперу з підвищеною водостійкістю як ерготерапії для людей з вадами розвитку. Було представлено виробництво паперу з використанням біорозкладних добавок та перевірено їхню гідрофобність за методом часу утримання краплі. Було виявлено, що папери, що містять агент, який використовувався для гідрофобізації, мали подовжений час утримання крапель. Ефективність функціоналізації структури паперу та гідрофобізатора підтверджено методом FTIR-спектроскопії. Механічні властивості всіх підготовлених зразків перевіряли, і було визначено, що функціоналізація натрієвою сіллю малеїнового ангідриду каніфолі Na-(RMA) дає кращі результати порівняно з абієтатом натрію (Na-Ab).

AB  - Multifunctional lignin bio-based adsorbent, b-LMS, was obtained via inverse copolymerization in the suspension of acryloyl modified kraft lignin (KfL-AA) and bio-based trimethylolpropane triacrylate (bio-TMPTA). Morphological and structural characterization of KfL-AA and b-LMS was performed using BET, FTIR, Raman, NMR, TGA, SEM, and XPS techniques. The b-LMS microspheres with 253 ± 42 μm diameters, 69.4 m2 g−1 surface area, and 59% porosity efficiently adsorb Malachite Green (MG), Tartrazine (T), and Methyl Red (MR) dye. The influence of pH, pollutant concentration, temperature, and time on the removal efficiency was studied in a batch mode. Favorable and spontaneous processes with high adsorption capacities e.g. 116.8 mg g−1 for MG, 86.8 mg g−1 for T, and 68.6 mg g−1 for MR indicate the significant adsorptive potential of b-LMS. Results from diffusional and single mass transfer resistance studies indicate that pore diffusion is a rate-limiting step. Theoretical calculations confirmed a higher affinity of b-LMS to cationic dye MG compared with an anionic and neutral one, i.e. T and MR, respectively. The data fitting from a flow system, using semi-empirical equations and Pore Surface Diffusion Modelling (PSDM) provided breakthrough point determination. The results from the desorption and competitive adsorption study proved the exceptional performance of b-LMS. Moreover, sulfation of b-LMS, i.e.production of b-LMS-OSO3H, introduced high-affinity sulfate groups with respect to cationic dye and cations. Developed methodology implements the principle of sustainable development and offers concept whose results contribute to the minimization of environmental pollution.

AB  - Vaccinium myrtillus L. (bilberry, Ericaceae), a perennial, wild, and small deciduous shrub that grows in the mountains and forests of Europe. The leaf extracts are widely used in traditional medicine due to their astringent, antiseptic, antioxidant, anti-inflammatory, hypolipidemic, and hypoglycemic activities. Microwave-assisted extraction provides various benefits, including reducing solvent consumption and extraction time and increasing extraction yield. In the present study, bilberry extracts were prepared using dried leaves, pure ethanol, or an ethanol-water mixture, and different temperatures in a microwave reactor (60, 100, and 160 ◦C). The extracts were examined in terms of total polyphenol content (TPC) and antioxidant activity. The TPC of the 96% ethanol extracts rose with the increase of the extraction temperature; the extract obtained at 60 ◦C (37.2 ± 0.5 mg gallic acid equivalents (GAE)/g of plant material)<the extract at 100 ◦C (46.6 ± 0.3 GAE/g)<the extract at 160 ◦C (55.1 ± 0.5 mg/g). The TPC of the 50% ethanol extract prepared at 60 ◦C was significantly lower (54.9 ± 1.0 mg GAE/g) in comparison to the extracts obtained at 100 and 160 ◦C (58.3 ± 1.0 and 58.0 ± 1.5 mg GAE/g, respectively). ABTS antioxidant capacity was higher in the 50% ethanol extracts compared to 96% ethanol parallels, while in the DPPH assay, there was no statistically significant difference between the 50 and 96% ethanol extracts. Due to higher TPC and anti-ABTS activity and reduced consumption of organic solvent, a 50% ethanol extract of V. myrtillus was favored, while the optimal temperature was 60 ◦C for the extract with the highest antioxidant capacity and 100 ◦C for the extract with the highest amount of polyphenols.
