AB  - The main biologically active components of plants belonging to the genus Allium, responsible for their biological activities, including anti-inflammatory, antioxidant and immunomodulatory, are organosulfur compounds. The aim of this study was to synthetize the mixture of dipropyl polysul-fides (DPPS) and to test their biological activity in acute hepatitis. C57BL/6 mice were administered orally with DPPS 6 h before intravenous injection of Concanavalin A (ConA). Liver inflammation, necrosis and hepatocytes apoptosis were determined by histological analyses. Cytokines in liver tissue were determined by ELISA, expression of adhesive molecules and enzymes by RT PCR, while liver mononuclear cells were analyzed by flow cytometry. DPPS pretreatment significantly attenuated liver inflammation and injury, as evidenced by biochemical and histopathological observations. In DPPS-pretreated mice, messenger RNA levels of adhesion molecules and NADPH oxidase complex were significantly reduced, while the expression of SOD enzymes was enhanced. DPPS pretreatment decreased protein level of inflammatory cytokines and increased percentage of T regulatory cells in the livers of ConA mice. DPPS showed hepatoprotective effects in ConA-induced hepatitis, charac-terized by attenuation of inflammation and affection of Th17/Treg balance in favor of T regulatory cells and implicating potential therapeutic usage of DPPS mixture in inflammatory liver diseases.

AB  - The presented study describes macroporous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) [PGME] functionalized with diethylenetriamine [PGME-deta] as a potential recovery agent for Mo(VI) oxyanions from aqueous solutions. Sorption studies were carried out by varying experimental conditions (pH, time, concentration, temperature). Kinetics of Mo(VI) sorption was investigated in batch (static) experiments, in the temperature range 298-343K. Sorption dynamics data were fitted to seven chemical-reaction and particle-diffusion models. The kinetics studies showed that Mo(VI) sorption adhered to the pseudo-second-order model under all investigated operating conditions. The sorption kinetics was determined to be governed by both the intraparticle diffusion and the external film diffusion to a lesser extent. The temperature rise promotes the molybdate species removal, with the maximum experimental uptake capacity of 4.02mmolg- 1 at 298K, at the selected pH which is consistent with the predominance range of hydrolized polynuclear Mo(VI) forms and optimum electrostatic attraction.

AB  - Evironmetally safe mortars in which part of the cement binder was replaced by mineral
additives (i.e. zeolite, bentonite and fly ash) were designed. Fly ash, as fine powdery byproduct
of coal combustion, comprises heavy metals in its composition. Bentonite and zeolite are natural
adsorbents with ability to immobilize certain toxic elements and prevent their migration from the
mortar structure. In this study the ability of bentonite and zeolite to adsorb toxic cations present in fly ash leachate was investigated. Metallic cations were detected in quantities not higher than 52.6, 15.5, 52.4 and 22.7 mg/kg for Zn, Pb, Cu and Ni respectively. Adsorption kinetic was
monitored using 0.1 mol/dm3 solutions of each of investigated cations (Zn2+, Pb2+, Cu2+ and
Ni2+) as well as multicomponent solution of all these cations during predefined time intervals in
the range from 10-1440 minutes. Adsorption isotherms were obtained in concentration range for
each cation of single and multicomponent solution in the range from 0.10-0.30 mol/dm3. The obtained
results of this investigation indicate that bentonite and zeolite are efficient adsorbents and,
therefore, they can be applied in combination with fly ash in environmentally-safe construction

AB  - Heteropoly acid (HPA) was supported on BEA zeolite by optimized synthesis method yielding samples containing different amounts (20 to 50 wt%) of 12-phosphotungstic acid (HPW). The prepared supported HPW samples were subjected to different post-synthesis procedures including calcination and ultrasonication resulting in BEA-HPW (BPW) hybrid materials. These BPW samples were characterized using SEM, N-2-sorption and electrical conductivity measurements. They were subsequently used for the preparation of composites with carbonized polyaniline synthesized in the presence of 5-sulfosalicylic acid, and studied as electrode materials for phenols sensing in acidic, neutral and alkaline media. Linear dependence of current on p-nitrophenol concentration in acidic media was obtained enabling evaluation of limit of detection. Composite electrode gave response to p-nitrophenol presence in alkaline media as well, while no response was recorded in neutral media. The work demonstrates benefits of using novel composite based on BPW hybrid materials and carbonized polyaniline for sensing of phenols in aqueous environmental samples.

AB  - The adsorption properties of two zeolite types, faujasite (NaY, ZnY, CoY) and LTA-4A zeolite (NaA, ZnA, CoA), towards technetium were studied in batch static experiments. The Si/Al ratio, acidity, dealumination, chargebalance cations of zeolite, contact time and temperature determined the adsorption efficiency. The maximum removal efficiency of 98.8% and K (d) value (2.06 x 10(-4) cm(3) g(-1)) was achieved using CoY (zeolite type Y). The kinetics of technetium adsorption followed the pseudo-second order model. The TcO2 adsorption is mainly due to the hydrogen bonds between protons of the zeolitic structural OH groups (Bronsted acid center) and oxygen from the TcO2 (-).

AB  - The disposal of waters contaminated with azo dyes into natural aquatic recipients can be
regarded as very harmful. Since dyes have a high degree of chemical and photolytic stability
adsorption can be regarded as appropriate method for dye removal. Porous alumina composites
are well known as efficient and inexpensive adsorbents of different pollutants. In this paper, the
alumina powders, pure and doped with 40 mass % nickel, were synthetized by sol-gel method
and calcined at 500 oC, 900 oC and 1100 oC in order to obtain mesoporous structures with a high
specific surface area, well adaptable to adsorption application. The obtained composites were
tested as adsorbents of textile azo dye Acid Yellow 99 (AY99). The adsorption was monitored
with respect to contact time, using AY99 initial concentrations of 50 mg dm-3, mass of adsorbent
mads=50 mg and volume of dye solution V=50 cm3. The adsorption study showed that the adsorption capacity of samples decreased with temperature of calcination and nickel content. The study confirmed the feasibility of using alumina composites as adsorbents for the azo dyes.

AB  - In this study, WO3 doped TiO2 powders were synthesized via sol-gel method combined with a hydrothermal process. The effect of sintering temperature on mesoporous structure and catalytic activities of these powders were investigated. The physical analysis via X-ray diffraction indicates that prepared samples are a mixture of anatase and rutile TiO2 phases. X-ray peak analysis is used to evaluate the crystallite size and lattice strain by the Williamson-Hall analysis. Considering all the reflections of the anatase phase the lattice strain ranging from c = 9.505 to c = 9.548 is calculated, suggesting that microstrain decreases when calcination temperature increases. N-2 adsorption-desorption analysis shows that the surface area and pore volume decrease with increasing temperature and that WOx-TiO2 powders primarily consist of mesopores. Sintering temperature induced a change in textural properties causing a systematic shift towards larger mesopores. Simultaneously, photoactivity in decolorization of methyl orange increases with increasing calcination temperature up to 700 degrees C, followed by significant decrease with its further increase.

AB  - Macroporous copolymers of poly[(glycidyl methacrylate)-co-(ethylene glycol dimethacrylate)] (PGME) with various crosslinker (ethylene glycol dimethacrylate) concentrations and porosity parameters and additionally functionalized with hexamethylene diamine (PGME-HD) were tested as potential Cr(VI) oxyanion sorbents from aqueous solutions. Kinetics of Cr(VI) sorption was investigated in the temperature range 298-343 K and the results were fitted to chemical reaction and particle diffusion models. The Cr(VI) sorption obeys the pseudo-second-order model with definite influence of pore diffusion. A temperature rise promotes chromium removal, with a maximum experimental uptake capacity of 4.21 mmol g(-1) at 343 K for the sample with the highest amino group concentration. Equilibrium data were analysed with Langmuir, Freundlich and Temkin adsorption isotherm models. Thermodynamic parameters, i.e. Gibbs free energy (G(0)), enthalpy (H-0) and entropy change (S-0) and activation energy of sorption (E-a), were calculated. The Cr(VI) adsorption onto PGME-HD was found to be spontaneous and endothermic, with increased randomness in the system. Desorption experiments show that chromium anion sorption was reversible and the PGME-HD sample GMA 60 HD was easily regenerated with 0.1 mol L-1 NaOH up to 90% recovery in the fourth sorption/desorption cycle. In the fifth cycle, a substantial sorption loss of 37% was observed.

AB  - This article presents the comparison of structural and fractal properties of nanocrystalline titanium dioxide (TiO2) and TiO2 modified with tungstophosphoric acid (TiO2/HPW) and their impact on the photocatalytic degradation of hazardous water pollutants. TiO2 and TiO2/HPW samples were synthesized by a combined solgel and hydrothermal processing. The XRD analysis of pure TiO2 samples revealed that phase composition was mainly dependent on the calcination temperature, changing from amorphous TiO2 to crystalline anatase and rutile by increasing the temperature. On the other hand, the XRD of TiO2/HPW samples calcined at temperatures above 600 degrees C showed crystalline peaks associated to formation of WO3 and WO2.92 crystalline domains. The N-2 adsorption-desorption isotherm and pore size distribution of TiO2/HPW samples detected the existence of mesoporous characteristic with very narrow bimodal pores in the mesoporous region. The structural heterogeneity of samples was analyzed by means of pore size distribution functions, while the variation in fractal dimension were determined from the nitrogen adsorption isotherms, using the modified Frenkel-Halsey-Hill method. The results demonstrate that the approach is capable of characterizing complex textures such as those present in the TiO2 and TiO2/HPW photocatalysts. Besides, the effect of calcinations condition on photocatalytic properties of the samples was also investigated. The highest efficiency with respect to methyl orange photodecomposition was observed for TiO2/HPW photocatalysts calcined at 700 degrees C.

AB  - The adsorptions of nicotine at 298 K from aqueous solution onto natural Wyoming
montmorillonite (Wy-M), acid-activated montmorillonite (Wy-MA) and alkali-activated
montmorillonite (Wy-MAL) were investigated. The Wy-MA and Wy-MAL samples were
obtained by acid and alkaline modification process using HCl and Na2CO3, respectively. The
changes in the chemical and phase composition, as well as the textural properties of the
starting and modified samples were monitored using X-ray diffraction, infrared spectroscopy
and physisorption of nitrogen. The adsorption experiments were performed in a batch system.
The adsorption was monitored with respect to contact time, nicotine initial concentrations
(0.1-1mM), mass of adsorbent (12.5 - 200 mg) and pH (2-11). The concentration of nicotine
was analyzed before and after the adsorption tests using a UV-Vis spectrophotometer at
λmax=261 nm. It was estimated that the equilibrium time for Wy-M and Wy-MAL was 60 min,
and 20 min for Wy-MA. The adsorption study showed that the alkaline modification of
montmorillonite slightly affected the adsorption of nicotine (qe = 0.27 and qe = 0.24 mmol/g,
for Wy-M and Wy-MAL, respectively). On the other hand, acid modification significantly
improved adsorption capacity of montmorillonite (qe= 0.52 mmol/g ). The adsorption results
were fitted by Langmuir, Freundlich and Sips adsorption isotherms.

AB  - This paper provides the correlation between the catalytic activity and selectivity of catalysts with various loadings of heteropolyacids over bentonite in the vapour phase 2-propanol oxidation. The catalysts are characterised by energy dispersive spectroscopy, differential scanning calorimeter, ammonia temperature programmed desorption, infrared spectroscopy and a nitrogen adsorption/desorption method. Energy dispersive spectroscopy results have shown satisfactory agreement regarding chemical composition that corresponds to the desired content of heteropolyacids on bentonite. Thermal analysis confirmed the thermal stability of catalysts under the investigated region of oxidation reaction. NH3-TPD spectra demonstrated that all catalysts include two types of acidic sites: weak adsorption centres up to 390 K and a broad distribution of stronger acidic sites at higher temperatures. The catalysts were active in the vapour-phase conversion of 2-propanol to acetone in the temperature region of 343-553 K. An increase of HPW loading improves selectivity towards acetone formation.

AB  - Inorganic modification of diatomite was performed with the precipitation product of partially neutralized aluminum sulfate solution at three different mass ratios. The starting and the modified diatomites were characterized by SEM-EDS, FTIR, thermal analysis and zeta potential measurements and evaluated for drug loading capacity in adsorption batch experiments using diclofenac sodium (DS) as a model drug. In vitro drug release studies were performed in phosphate buffer pH 6.8 from comprimates containing: the drug adsorbed onto the selected modified diatomite sample (DAMD), physical mixture of the drug with the selected modified diatomite sample (PMDMD) and physical mixture of the drug with the starting diatomite (PMDD). In vivo acute toxicity testing of the modified diatomite samples was performed on mice. High adsorbent loading of the selected modified diatomite sample (similar to 250 mg/g in 2 h) enabled the preparation of comprimates containing adsorbed DS in the amount near to its therapeutic dose. Drug release studies demonstrated prolonged release of DS over a period of 8 h from both DAMD comprimates (18% after 8 h) and PMDMD comprimates (45% after 8 h). The release kinetics for DAMD and PMDMD comprimates fitted well with Korsmeyer-Peppas and Bhaskar models, indicating that the release mechanism was a combination of non-Fickian diffusion and ion exchange process.

AB  - Biomorphous beta-SiC ceramics were produced from several species of wood such as ash, wild cherry, black alder, Persian walnut, sessile oak and European hornbeam. The wood was pyrolysed, impregnated with tetraethyl orthosilicate (TEOS) sol in repeated cycles and thermally treated at 1800 degrees C in vacuum. Four specimen groups included charcoal and three groups with 1, 3 and 5 cycles of impregnation were analyzed. Flexural and compressional strength of charcoal and woodlike SiC ceramics were measured using three-point and compression testing in different directions. Experimental results showed that mechanical properties of woodceramics were improved by repeating of impregnation cycles. Porosity measurement, dilatometric analysis, XRD and SEM analysis were used to study the macroscopical and microscopical properties of the resulting biomorphic SiC ceramics.

AB  - Nanostructured and granular polyanilines (PANIs) and their composites with zeolite ZSM-5, synthesized by the oxidative polymerization of aniline in water and aqueous solution of sulfuric acid, are evaluated as adsorbents of the organic herbicide glyphosate [N-(phosphonomethyl)glycine] in aqueous solution. The protonated and deprotonated forms of synthesized materials were characterized by elemental and thermogravimetric analysis, scanning electron microscopy, FTIR, Raman and UV-Vis spectroscopies, X-ray powder diffraction, and nitrogen physisorption measurements. The adsorption isotherms of glyphosate on studied materials were best fitted by Freundlich and Langmuir-Freundlich models. The adsorption characteristics of the investigated PANIs and PANI/ZSM-5 composites were found to be much more influenced by the oxidation state and protonation level of PANI in the adsorbents then by the textural and morphological properties of materials. The highest adsorption of glyphosate among all investigated PANI and PANI/ZSM-5 samples, as well as pure ZSM-5, exhibited the deprotonated granular PANI which was synthesized in sulfuric acid medium (98.5 mg/g). High adsorption capacity also showed the deprotonated PANI/ZSM-5 composite with similar to 50% of zeolite (61.9 mg/g) and the protonated nanostructured PANI (59.9 mg/g), both materials prepared in water without added acid.

AB  - The influence of contact time, temperature and particle size on lead sorption by the natural and Fe(III)-modified zeolites was investigated. Characterization of the natural and Fe(III)-modified zeolite before and after lead sorption was performed by determination of textural properties, by scanning electron microscopy and X-ray spectroscopy in energy-dispersive mode (SEM-EDS), transmission electron microscopy (TEM) and X-ray powder diffraction (XRPD) analysis. Lead sorption kinetics at 303-333 K, best represented by the pseudo-second order model and activation energy (13.5 and 8.5 kJ/mol for the natural and Fe(III)-modified zeolite respectively) confirmed an activated chemical sorption. Desorption experiments indicated that lead was irreversibly sorbed on both zeolites. XRPD, TEM and SEM results showed that modification of the natural zeolite with Fe(III) ions did not change its crystal structure and iron is mainly located at the zeolite surface, likely in form of amorphous iron oxy-hydroxides. Specific surface area significantly increases after modification of the natural zeolite with Fe(III) ions (from 30.2 for the natural to 52.5 m(2)/g for Fe(III)-modified zeolite). Characterization of both lead saturated sorbents suggested that besides ion exchange, lead is both chemisorbed and precipitated at their surfaces, and presence of amorphous iron in Fe(III)-modified zeolite favors sorption of lead.

AB  - Two porous and one non-porous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) [abbreviated PGME] were prepared by suspension copolymerization and functionalized with diethylene triamine [abbreviated PGME-deta]. Samples were characterized by elemental analysis, mercury porosimetry, scanning electron microscopy with energy-dispersive X-ray spectroscopy, and transmission electron microscopy. Kinetics of Cr(VI) sorption by PGME-deta were investigated in batch static experiments, in the temperature range 25-70 degrees C. Sorption was rapid, with the uptake capacity higher than 80% after 30 min. Sorption behavior and rate-controlling mechanisms were analyzed using five kinetic models (pseudo-first order, pseudo-second order, Elovich, intraparticle diffusion and Bangham model). Kinetic studies showed that Cr(VI) adsorption adhered to the pseudo-second-order model, with definite influence of pore diffusion. Equilibrium data was tested with Langmuir, Freundlich and Tempkin adsorption isotherm models. Langmuir model was the most suitable indicating homogeneous distribution of active sites on PGME-deta and monolayer sorption. The maximum adsorption capacity from the Langmuir model, Q(max),at pH 1.8 and 25 degrees C was 143 mg g(-1) for PGME2-deta (sample with the highest amino group concentration) while at 70 degrees C Q(max) reached the high value of 198 mg g(-1). Thermodynamic parameters revealed spontaneous and endothermic nature of Cr(VI) adsorption onto PGME-deta.

AB  - The possibility of sorption of technetium-99 in the form of pertechnetate anion (TcO(4)(-)) and the sorption kinetics for removing TcO(4)(-) from aqueous solution by chelating polymers based on glycidyl methacrylate (GMA) were investigated. Two samples of macroporous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) (PGME), with different amount of the crosslinker (ethylene glycol dimethacrylate, EGDMA), were synthesized by suspension copolymerization and functionalized with diethylene triamine (deta). We propose that nonspecific sorption of pertechnetate anion via electrostatic interactions takes place at the protonated amino groups of macroporous crosslinked copolymer. The results of batch experiments per-formed at pH 1-14 showed fast sorption kinetics for removing TcO(4)(-) by amino-functionalized PGME-deta in a wide range of pH, that is, from 1.0 to 9.0. Almost complete removal of TcO(4)(-) (91-98%) was reached within 180 min in the stated pH range (1.0-9.0), with the sorption half-times of under 25 min. The partitioning coefficients of linear adsorption isotherms, with 180-min equilibrium time, reach the high values of 2130 mL g(-1) and 1698 mL g(-1) for the two samples of synthesized PGME-deta.

AB  - Technetium-99 comprises a significant health risk, since edible plants can bioaccumulate and convert it to more lipophilic species that cannot be excreted through urine. Batch kinetics of pertechnetate removal from aqueous solutions by two samples of crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) functionalized with diethylene triamine (PGME-deta) was investigated at the optimum pH value of 3.0, and the initial solution activity of 325 MBq dm(-3). PGME-deta was characterized by elemental analysis, mercury intrusion porosimetry, and scanning electron microscopy. Five kinetic models (pseudo-first, pseudo-second order, Elovich, Bangham, and intraparticle diffusion) were used to determine the best-fit equation for pertechnetate sorption. After 24 h, PGME-deta samples sorbed more than 98% of pertechnetate present, with maximum sorption capacity of 25.5 MBq g(-1), showing good potential for remediation of slightly contaminated groundwater.
