AB  - Aniline, the main representative of aromatic amines, occurs in a large number
of industries, such as the production of textiles, plastics, medicines, pesticides,
rubber, and varnishes.1 Due to practicality and efficiency, a molecularly imprinted
polymers (MIPs) can be used as sorbents for removing aniline.2 In this study,
magnetic molecularly imprinted polymer was synthesized via suspension
copolymerization while characterization was performed by various methods in order
to obtain an efficient sorbent for the aniline removal from an aqueous solution.
Fourier transform infrared spectroscopy (FT-IR) confirmed characteristic vibrational
bands which suggested successful synthesis of MIP, nitrogen gas adsorption-desorption
measurements as well as mercury porosimetry have shown that the most
dominant pores were mesopores, while scanning electron microscopy with energy
dispersive X-ray spectroscopy (SEM-EDX) confirmed a 3D spherical porous
structure with all the expected elements.

AB  - Macroporous (glycidyl methacrylate) GMA-based composite was
synthesized via suspension polymerization in the presence of 2 wt. % magnetic
nanoparticles and functionalized with triethylenetetramine. Copper was immobilized
on composite by contacting modified copolymer with 0.1 M solution of CuCl2, at pH
5, and 25 ̊C. The obtained composite was characterized by mercury porosimetry,
Fourier transform infrared spectroscopy (FTIR) analysis and atomic force
microscopy (AFM). GMA-based composites, due to their properties (size, porosity,
etc.), and the presence of reactive epoxy group, have found a variety of applications
as sorbents, enzyme supports, in biomedical applications, for metal and organic
compounds sorption.1
The antimicrobial activity of the synthesized GMA/Cu copolymer against
Staphylococcus aureus, Escherichia coli, Candida albicans and Aspergillus niger as
representatives for Gram-positive bacteria, Gram-negative bacteria, yeast and fungi
were investigated in this study.2 The copolymer displayed good antimicrobial activity
against all analyzed microbes, which makes it a material that can be potentially used
for biomedical (antibacterial and antifungal) applications.

AB  - In the present study, synthesized macroporous copolymer was used for the sorption of lindane
from an aqueous solution. This organochlorine pesticide is classified, according to US EPA, as
mutagenic and teratogenic. Residues of lindane can persist in the environment, migrate long
distances, and cause widespread contamination. In this way, lindane residues can reach the
human body through the food chain. The usage of this pesticide is banned in most countries.
However, lindane remains a serious toxicological problem at industrial sites where lindane was
used coupled with improper wastewater disposal and has led to serious contamination. In
addition, some countries still allow the production and use of lindane, and despite localized
restrictions, lindane contamination remains a global problem. Taking into account these
reasons, its removal from the environment is of a great significance. The obtained macroporous
copolymer was syntesized via suspension copolymerization and was characterized by Fourier
transform infrared spectroscopy (FT-IR), and scanning electron microscopy (SEM). The
parameters which affect sorption efficiency of the lindane were: pH, sorption time (tsor), ion
strength (ion), rpm, and dose of sorbent. These variables were optimized by the experimental
design which include Plackett-Burman Design (PBD) and Central Composite Design (CCD).
After screening step by the PBD, the optimum conditions were obtained by the CCD where the
values were investigated in two levels. The design of experiment showed that the ion strength
and dose of sorbent were the most significant parameters, while the other variables do not have
such an effect on sorption efficiency. Accordingly, the optimum conditions to reach the maximum
recovery were: pH 8, 180 min sorption time, 300 rpm, 2 w/v % ion strength and 8 g/l dose of
sorbent. The results showed that the studied copolymer could be an efficient sorbent for trace
lindane in water with recoveries above 80 %.

AB  - Lindane was one of the most commonly used organochlorine pesticides for controlling a wide
range of horticultural, agricultural, and public health pests during the second half of the 20th
century. [1] Owing to its toxic nature, bioaccumulation capability, and long transportable
nature, it belongs to a group of persistent organic pollutants (POPs). [2] Although lindane use
has been restricted or even banned, its residues persist and represent a serious environmental
problem since lindane residues are still found in water, sediments, soil, plants, and
animals. [3] Therefore, there is a growing interest in lindane removal or degradation by various
methods. In this context, sorption has received considerable attention as one of the most
effective and simplest technological approaches for the removal of lindane. In the present
study, we investigated the kinetics of the lindane sorption process onto a porous
functionalized copolymer based on glycidyl methacrylate. Five widely used isotherm kinetic
models (pseudo-first-order, pseudo-second-order, Elovich, Avrami, and fractional power
models) were employed via non-linear and linear fitting. The extent of kinetic model
compatibility was evaluated through seven error functions. According to the obtained results,
the pseudo-second-order model was the best-fitting kinetic model for describing the kinetics
of lindane sorption by the investigated sorbent.

AB  - Organohlorni pesticid - lindan, smatra se potencijalno kancerogenim jedinjenjem. Lindan i
njegovi ostaci mogu da opstanu u životnoj sredini veoma dugo, migrirajući i potencijalno
izazivajući zagađenje životne sredine. Ostaci lindana mogu dospeti i u ljudski organizam
kroz lanac ishrane, jer je ovo potencijalno toksično jedinjenje sklono bioakumulaciji.
Kontaminacija lindanom je globalni problem, a njegovo uklanjanje iz životne sredine je
neophodno. U ovom istraživanju sorpcija lindana iz vodenog rastvora urađena je sa
makroporoznim kopolimerom na bazi glicidil metakrilata, koji se pokazao kao veoma
efikasan sorbent, sa sorpcijom lindana od oko 0%. Za određivanje koncentracije lindana
korišćena je analitička tehnika, gasna hromatografija sa detektorom za hvatanje elektrona
GC-ECD. Osim sorpcije, uspešno je urađena i desorpcija lindana.
AB  - Organochlorine pesticide - lindane, is considered as potentially carcinogenic compound.

AB  - Organochlorine pesticide - lindane, according to the US EPA classification, is considered
as potentially carcinogenic compound. Although the usage of this pesticide is banned in
many countries, it is still used in some. As persistent organic compound, lindane and its
residues can persist in the environment for a very long time, migrating over long distances,
potentially causing environmental pollution. Lindane residues can reach the human body
through the food chain, because this potentially toxic compound is prone to
bioaccumulation, and this is serious toxicological problem especially at industrial and
agricultural sites where lindane has been used directly, or has reached due to improper
wastewater disposal. Despite bans on its use, lindane contamination remains a global

AB  - Lindane belongs to the persistent organic pollutants (POPs) group, which can cause carcinogenic, endocrine, and neurological problems in an organism. The widespread presence of lindane in the environment demands efficient methods of its removal. In the present work, we investigated the removal of lindane from an aqueous solution using a synthesized macroporous copolymer surface modified with different functional groups through two-step post-functionalization. The modified copolymer was characterized by Fourier transform infrared spectroscopy (FTIR-ATR), scanning electron microscopy (SEM), and mercury intrusion porosimetry. For the kinetics of lindane sorption, pseudo-first-order, pseudo-second-order, Elovich, Avrami, and fractional power models were used via linear and non-linear regression analyses. The quality of the fitting of each model to experimental data was assessed based on seven error functions: coefficient of determination (R2), Marquardt’s percent standard deviation (MPSD), Chi-square statistic test (χ2), hybrid fractional error function (HYBRID), the sum of the errors squared (SSE), sum of the absolute errors (EABS), and average relative error (ARE). The investigation of error estimation methods showed that the pseudo-second-order model best fits the experimental kinetics data for both regression analyses. The mechanism of lindane sorption was investigated by subjecting the data to the liquid film diffusion model, intraparticle diffusion model, Bangham, and Boyd models. The results showed that intraparticle diffusion was not the sole rate-controlling step; film-diffusion also affected the sorption process.

AB  - Hexavalent chromium, Cr(VI), is one of the most notorious pollutants with
health and environmental impacts due to carcinogenic, teratogenic, and mutagenic
effects on the human organism.1 Therefore, treating wastewater containing Cr(VI)

nonlinear regression method was used to determine the kinetic and isotherm
parameters for Cr(VI) sorption from aqueous solution on hexamethylene diaminemodified 177btain177177ous copolymer based on glycidyl methacrylate (PGEHMD).2 The Avrami kinetic model provides the best correlation of the experimental data with R2 = 0.994 and χ2 = 0.004, while the Freundlich isotherm model best described the Cr(VI) sorption onto PGE-HMD copolymer indicating a heterogenous sorption process.

AB  - Deep eutectic solvents (DESs) have been recognized as promising solvents due to their purity, high conductivity, bio-degradability, thermal stability1. These environmentally friendly solvents are important tools in the creation of green and sustainable technologies. The use of DES in polymer science is highly promising for the development of novel green materials. Therefore, DESs have been used in molecular imprinting in order to improve the properties of molecularly imprinted polymers (MIP). DES are most often prepared by combining two classes of compounds: hydrogen bond donor, HBD (such as amide) and hydrogen bond acceptor, HBA (such as quaternary ammonium salt) in different molar ratios2. By mixing these components in with appropriate molar ratios, eutectic mixtures are formed in a liquid state at temperatures below 100 °C. This study reports the ability of DES-MIP as a sorbent for the removal of aromatic amine from plastic packaging. In order to obtain the most effective sorbent, DESs are prepared by combining choline chloride as HBA with different HBDs, such as urea, glycerol, and ethylene glycol. The results showed that choline chloride:urea was the most suitable DES as modifier of MIP.

AB  - Cross-linked macroporous copolymers based on glycidyl methacrylate (GMA) have
been used as sorbents for metals, support for enzymes, as biomaterials etc. In this
research GMA copolymer was prepared by copolymerization of GMA (glycidyl
methacrylate) and EGDMA (ethylene glycol dimethacrylate), in the presence of inert
component (90 mass% of cyclohexanol and 10 mass% of dodecanol), and functionalized
with diethylenetriamine (DETA). Presence of epoxy groups in GMA-based copolymers
allows chemical modifications on the polymer in order to achieve its different
applications. GMA-based copolymer was activated with 0.1 M solution of Ga(NO3)3, at
pH 3, and 25 °C [1].
Antimicrobial activity of functionalized and activated GMA-based copolymer,
GMA/Ga, was analyzed against Staphylococcus aureus (Gram positive bacteria),
Escherichia coli (Gram negative bacteria), Candida albicans (yeast) and Aspergillus
niger (fungi) [2]. The agar-well diffusion method was used to evaluate antimicrobial
activity of GMA/Ga polymer. Nutrient agar plates were inoculated with broth of 1 MFU
microbial suspensions. Wells of 5 mm diameter were punched in the inoculated plates
using a sterile metallic borer, and then filled with 100 μL of water solution containing
nanoparticles of GMA/Ga copolymer, at various concentrations: 10, 20, and 30 mg/mL.
Control wells were filled with 100 μL of distilled water. Inoculated plates were incubated
at 37 °C/24 h for bacteria and yeast, and at 30 °C/48 h for fungus. Antimicrobial activity
of Ga activated copolymer was evaluated by measuring the inhibition zone diameter
around the wells. The GMA/Ga copolymer displayed good antimicrobial activity against
Escherichia coli and Candida albicans, which makes it selective for Gram negative
bacteria and yeasts, and as a material that can be potentially used for biomedical
applications, in food industry etc.

AB  - This study evaluated the equilibrium, kinetics, and thermodynamics of vanadium sorption from aqueous solution onto nanocomposite functionalized with diethylene triamine in batch conditions. The effects of temperature, solution pH, and initial concentration of vanadium were examined. The maximum sorption capacity of vanadium on the tested sorbent was achieved at pH 6. The sorption capacity increased with increasing temperature and initial concentration. The equilibrium adsorption data were analyzed using Langmuir, Freundlich, Temkin, Jovanovic, Toth, Sips, Khan, and Redlich-Peterson isotherm models. The kinetics data were studied using pseudo-first-order, pseudo-second-order, the fractional power, Elovich, and Avrami models. A non-linear fitting method was used to compare the best fitting of the equilibrium and kinetic data. The sorption equilibrium data were best represented by the Langmuir, Khan, Toth, and Redlich–Peterson isotherms. The adsorption kinetics was estimated to follow the pseudo-second-order kinetic model. The mechanism of vanadium sorption was analyzed with intra-particle, Bangham, Boyd, and liquid film diffusion models. It was observed that the sorption process was controlled by the film-diffusion as well as the pore-diffusion. Thermodynamic parameters (change of standard enthalpy (ΔH°), standard entropy (ΔS°), and standard free energy (ΔG°)) suggested that the sorption of vanadium onto functionalized nanocomposite was a spontaneous and endothermic process.

AB  - Silver as one of the most known precious metal is used on a large scale in various industrial
branches and the release of silver ions from such industrial activities potentially can cause
serious environmental problems. Therefore, the removal of this metal from wastewater is a great
challenge, and it is crucial for the quality improvement of the environment. Porous polymer
materials with high specific surface areas and other specific physical and chemical
characteristics have gained much attention as sorbents in the field of environmental protection.
In this paper, macroporous poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate)
copolymer synthesized by suspension copolymerization and functionalized with
diethylenetriamine was employed for silver ions sorption from aqueous solution at unadjucted
pH and room temperature. The sorption kinetics and isotherms were studied to establish the
mechanisms of sorption process. The kinetic data were modeled with pseudo-first-order (PFO),
pseudo-second-order (PSO), Elovich and fractional power (FP) models as well as intraparticle
diffusion (IPD) and liquid diffusion model (LFD), while the equilibrium data were analized
using Langmuir, Freundlich, Sips and Redlich-Peterson isotherm models. Eight error functions
such as coefficient of determination (R2), Marquardt’s percent standard deviation (MPSD), Chisquare
statistic test (χ2), hybrid fractional error function (HYBRID), the root mean square error
(RMSE), the sum of the errors squared (SSE), sum of the absolute errors (SAE), and average
relative error (ARE) were used to estimate the error deviations between theoretically predicted
and experimental values of sorption capacities. The best kinetic and isotherm models were
determined by normalizing eight error functions and finding the sum of normalized error value
(SNE). The sorption kinetic studies revealed that the sorption of silver by macroporous aminofunctionalized
sorbent obeys the PSO kinetic model. In addition, the results indicate that
sorption was governed by intraparticle diffusion with the evident influence of liquid film
diffusion. The obtained results showed that the sorption isotherm data were satisfactorily fitted
to the Redlich-Peterson isotherm model.

Trivalent Cr(III) and hexavalent Cr(VI) are the most common forms found in effluent water. Whereas trivalent chromium is a micronutrient (25–35 g/day) involved in the metabolism of lipids and carbohydrates [3,4], hexavalent chromium is exceedingly toxic, teratogenic, and mutagenic. Particularly concerning are its high solubility in water, mobility in detritus, and potential for bioaccumulation in living tissues. Due to these factors, hexavalent chromium has been the subject of numerous studies, especially its removal from effluent [5,6]. These studies have demonstrated that sorption is a highly effective and relatively simple technique for chromium removal from wastewater. In terms of this, magnetic heavy metals nanosorbents derived from inorganic compounds and polymers [7-9] are incredibly intriguing, because they could have been readily extracted from the mixture using an external magnetic field. The sorption investigation of hexavalent chromium in aqueous solutions on the magnetic aminofunctionalized polymer nanocomposite based on glycidyl methacrylate, m-PGMA revealed its highly selectivity and efficiency. [10,11]. The binding mechanism of hexavalent chromium ions onto m-PGMA was investigated using kinetic, equilibrium, and thermodynamic experiments as well as molecular modeling techniques (theoretical quantum-chemical calculations) [12-15]. It was observed that the process occurs in two phases. In the first phase, electrostatic interactions attract hexavalent chromium ions to the surface of the sorbent via the active sites (amino and APTMS groups). Cr(VI) is then converted to Cr(III) ions, which can coordinate with amino or hydroxyl groups on the surface of the sorbent [16]. The trivalent chromium ions that persist in the solution or on the surface of the sorbent are less hazardous than the initial hexavalent form. The application of m-PGMA sorbent enables the transformation of the toxic form of chromium into a less hazardous form, which is significant due to the possibility of sorbent regeneration and the subsequent processing of the solution following sorption.

AB  - Silver as one of the most known precious metal is used on a large scale in various industrial
branches and the release of silver ions from such industrial activities potentially can cause
serious environmental problems. Therefore, the removal of this metal from wastewater is a great
challenge, and it is crucial for the quality improvement of the environment. Porous polymer
materials with high specific surface areas and other specific physical and chemical
characteristics have gained much attention as sorbents in the field of environmental protection.
In this paper, macroporous poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate)
copolymer synthesized by suspension copolymerization and functionalized with
diethylenetriamine was employed for silver ions sorption from aqueous solution at unadjusted
pH and room temperature. The sorption kinetics and isotherms were studied to establish the
mechanisms of sorption process. The kinetic data were modeled with pseudo-first-order (PFO),
pseudo-second-order (PSO), Elovich and fractional power (FP) models as well as intraparticle
diffusion (IPD) and liquid diffusion model (LFD), while the equilibrium data were analized using
Langmuir, Freundlich, Sips and Redlich-Peterson isotherm models. Eight error functions such as
coefficient of determination (R2), Marquardt’s percent standard deviation (MPSD), Chi-square
statistic test (χ2), hybrid fractional error function (HYBRID), the root mean square error
(RMSE), the sum of the errors squared (SSE), sum of the absolute errors (SAE), and average
relative error (ARE) were used to estimate the error deviations between theoretically predicted
and experimental values of sorption capacities. The best kinetic and isotherm models were
determined by normalizing eight error functions and finding the sum of normalized error value
(SNE). The sorption kinetic studies revealed that the sorption of silver by macroporous
amino-functionalized sorbent obeys the PSO kinetic model. In addition, the results indicate that
sorption was governed by intraparticle diffusion with the evident influence of liquid film
diffusion. The obtained results showed that the sorption isotherm data were satisfactorily fitted
to the Redlich-Peterson isotherm model.

AB  - A novel porous gold polymer composite was prepared by the functionalization of a glycidyl methacrylate-based copolymer (pGME) with ethylene diamine (pGME-en), and activation by gold (pGME-en/Au), in a simple batch adsorption procedure in an acid solution, at room temperature. Detailed characterization of the pGME-en before and after activation was performed. The main focuses of this research were the design of a method that can enable the recovery of gold and the reuse of this multipurpose sorbent as an antimicrobial agent. Fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS) analysis pointed out amine groups as the primary binding sites for Au activation, while hydroxyl groups also contributed to the chelation reaction. pGME-en exhibited fast gold adsorption with an adsorption half-time of 5 min and an equilibrium time of 30 min. The maximal adsorption capacity was about 187 mg/g. The analysis of sorption experimental data with a non-linear surface reaction and diffusion-based kinetic models revealed the pseudo-second-order and Avrami model as the best fit, with unambiguous control by liquid film and intra-particle diffusion. The biological activity studies against Staphylococcus aureus, Listeria monocytogenes, Escherichia coli, and Candida albicans revealed moderate activity of pGME-en/Au against different bacterial and fungal species. pGME-en/Au was stable in a saline solution, with a release of approximately 2.3 mg/g after 24 h.

AB  - A new magnetic amino-functionalized polymeric sorbent based on glycidyl methacrylate was synthesized and used in the separation of chromium Cr(VI) oxyanions sorption from aqueous solutions in a static batch system. The kinetic and isothermal parameters of the sorption process were determined. The experimental data were best fitted by a pseudo-second-order model with R2 = 0.994 and χ2 = 0.004. The sorption process of Cr(VI) removal by amino-functionalized sorbent was controlled by both intraparticle diffusion and liquid film diffusion. The equilibrium results showed that the sorption process is best described by the Freundlich model, followed closely by the Sips isotherm model, with a maximum sorption capacity of 64 mg/g. Quantum chemical modeling revealed that the sorption sites on the sorbent surface are fragments with diethylenetriamine and aminopropyl silane groups that coated the magnetic nanoparticles. The calculations showed that Cr(VI) oxyanions (Cr2O72−, CrO42− and HCrO4−) bind to both sorption sites, with diethylenetriamine centers slightly favored. The X-ray photoelectron spectroscopy (XPS) spectra demonstrate that the chromium bound to the sorbent in the form of Cr(III), indicating that the Cr(VI) can be converted on the surface of the sorbent to a less harmful form Cr(III) due to the sorbent’s chemical composition.

AB  - In this paper, three molecularly imprinted polymers (MIPs) with different molar ratios of amine (ethylene diamine) and template (aniline) (1:1, 2:1, 4:1) were synthesized by the surface imprinting method. The obtained MIPs were characterized by scanning electron microscopy and FTIR, and investigated as a potential aniline sorbents at different pH. The results showed that MIP (4:1) had good potential for the removal of aniline.

AB  - Kinetic, equilibrium and thermodynamic of arsenate sorption onto magnetic polymer sorbent based on glycidyl methacrylate were investigated. The maximum sorption capacity of 0.59 mg/g was obtained. The experimental data were analyzed by seven kinetic models and eight isotherm models. Nonlinear regression method was used to fit the data to the kinetic and isotherm models. Thus, two error functions; coefficient of determination and Chi-square statistic test were applied to evaluate the sorption data. It was shown that arsenate sorption obeys the pseudo-second-order model with evident influence of pore and film diffusion. The Freundlich and all three-parameter isotherm models proved to be the best representatives of arsenate sorption. Thermodynamic studies implied endothermic and spontaneous process in nature.

AB  - In this report, magnetic porous polymer functionalized with pentaethylenehexamine (mP-PEHA) was tested as CO2 sorbent. The sorbent mP-PEHA was characterized by Fourier transform infrared spectroscopy in ATR mode (FTIR-ATR), scanning electron microscopy (SEM) and mercury porosimetry. CO2 adsorption was determined using a pulse gas chromatographic method. At optimal adsorption conditions (20 °C), the CO2 sorption capacity reached 10.8 ml CO2/g (0.48 mmol CO2/g). Temperature-programmed desorption (TPD) experiments were conducted to calculate the activation energy of CO2 desorption. Low activation energy (18.34 kJ/mol) and high desorption rate, with a stable uptake in five adsorption/desorption cycles, suggest mP-PEHA as potentially excellent sorbent for CO2 absorption.

AB  - Magnetic macroporous poly(glycidyl methacrylate-co-trimethylolpropane trimethacrylate) nanocomposite was synthesized by suspension copolymerization. The obtained nanocomposite was characterized by Fourier transform infrared spectroscopy (FT-IR), mercury porosimetry and scanning electron microscopy (SEM). Such magnetic nanocomposite was applied as sorbent for a dispersive solid-phase microextraction (DSPME) for aniline preconcentration from water samples. The parameters affecting the microextraction were optimized. The screening of DSPME parameters was determined using Plackett-Burman design (PBD). For the optimization of the most important factors Central Composite Design (CCD) was used. The analysis of the results showed that the pH value and temperature of desorption were the most significant factors.

AB  - Improving the affinity and selectivity of polymeric materials for sorbing ionic species, particularly
heavy metals that pose a high environmental risk, is crucial from an environmental standpoint.
Research on the mechanism of sorption can aid in selecting the optimal sorbent for a given
application. Sorption occurs as a result of various interactions. Sorption includes diffusion of ions
through solution (typically the quickest), diffusion of ions through the boundary layer surrounding
the sorbent surface, diffusion through the porous structure of the sorbent (intra-particle diffusion),
and binding to active sites on sorbent surfaces. Kinetic and equilibrium models explain the sorption
mechanism but not the nature of interactions, which is essential for predicting the selectivity and
efficiency of the sorbent based on particular ionic species. As a result, we were compelled to
approach the molecular level. Active sites on the surface of the magnetic aminofunctionalized
polymer, which are amino functional groups, are used to bind ions to the magnetic nanocomposite.
The sorption process can be viewed as the sum of ion-ligand unit interactions. Unit complex
formation and stability can be studied with statistical analysis and quantum chemical calculations.
The Cambridge database (CSD) improves the crystal structure of complex ion-ligand. Based on
binding energy, DFT (Density Functional Theory) predicts the stability of complex molecules (unit
ion-ligand interactions). To ensure an accurate calculation, it is essential to include all system
parameters, including sorbent structure, ligand properties, ligand charge under specific conditions,
ion forms and charges, and solvatation effects. In the early stages of research, defining the system's model lets researchers make theoretical predictions about the magnetic aminofunctionalized polymer sorbent's affinity and selectivity for certain ionic species.
