AB  - The contamination of water with chromium is a global issue that is especially
severe in developing countries with intensive mining and heavy industry (South
Africa, Pakistan, and India) [1,2]. 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  - 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  - A core-shell amino-functionalized glycidyl methacrylate magnetic molecularly imprinted polymer (MIP) was synthesized by the suspension polymerization/surface imprinting method and characterized by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), mercury porosimetry, nitrogen gas adsorption–desorption, and elemental analysis. This MIP was used as the sorbent in dispersive solid-phase microextraction (DSPME) of aniline from textile wastewater prior to high-performance liquid chromatography-mass spectrometry (HPLC-MS) measurements. Since aniline is toxic and a probable human carcinogen, its determination in water is of great significance. This is a challenging task because aniline is usually present at trace levels. The effects of different DSPME variables on the preconcentration efficiency have been studied by using the Plackett–Burman screening design of experiments (DoE) followed by response surface methodology optimization using the Box-Behnken design. Thus, DoE enabled the investigation of several variables simultaneously. Under optimized conditions, aniline was effectively and selectively separated by a small amount of the DSPME sorbent and detected in real textile wastewater samples. The method detection limit of 1 ng mL−1 was attained, with good method linearity and acceptable recovery and precision. The results showed that the studied MIP could be a reliable DSPME sorbent for efficiently analyzing trace aniline in real wastewater samples.

AB  - The industrialization and urbanization expansion have increased the demand for precious and rare earth elements (REEs). In addition, environmental concerns regarding the toxic effects of heavy metals on living organisms imposed an urgent need for efficient methods for their removal from wastewaters and aqueous solutions. The most efficient technique for metal ions removal from wastewaters is adsorption due to its reversibility and high efficiency. Numerous adsorbents were mentioned as possible metal ions adsorbents in the literature. Chelating polymer ligands (CPLs) with adaptable surface chemistry, high affinity towards targeted metal ions, high capacity, fast kinetics, chemically stable, and reusable are especially attractive. This review is focused on methacrylatebased magnetic and non-magnetic porous sorbents. Special attention was devoted to amino-modified glycidyl methacrylate (GMA) copolymers. Main adsorption parameters, kinetic models, adsorption isotherms, thermodynamics of the adsorption process, as well as regeneration of the polymeric sorbents were discussed.

All orientations of PBISe areclustered at the same site (active site, Figure) leading to much better efficiency of this moleculecompared to PBIT, where three binding sites can be observed (Figure).

AB  - With regard to the harmful effects of heavy metals on human health and the environment, the demand for synthesis and investigation of macromolecules with large capacity of harmful substances sorption is ever greater. Quantum-chemical methods may be applied in structural modeling, prediction, and characterization of such molecules and reactions. Sorption of metal ions (Cu2+, Cd2+, Co2+, and Ni2+) to triethylenetetramine-functionalized copolymer poly(GMA-co-EGDMA)-teta was successfully modeled by quantum chemical calculations, at the B3LYP//6-311++G**/lanl2dz level. Optimized structures of metal complexes were used for calculation of real binding energy of metal ion within the complex (Er). Solvent and hydrolyzation effects were essential for obtaining the objective values. Solvent effect was included in Er by using the total solvation energy for reaction of formation of tetaOH complex (Es1, the first approach) or by using dehydration energy of free metal ion (Es2, the second approach). Experimental results were confirmed in our theoretical analyses (using the second approach).

AB  - Polymer-based, highly porous nanocomposites with functionalized ligands attached to the core structure are extremely efficient in the detection, removal and recovery of metals through the process of sorption. Quantum-chemical models could be helpful for sorption process analyses. The sorption of Cu(II) ions by amino-functionalized chelating macroporous copolymers poly(GMA-co-EGDMA)-amine and sorption selectivity of the subject copolymers, ethylenediamine (en), diethylenetriamine (dien) and triethylenetetramine (trien), were successfully modelled by quantum chemical calculations. Considering the crystal structures from CSD and experimental conditions during the formation of metal complexes, the most frequent mononuclear complexes are those with the tetradentate teta ligand, while binuclear complexes are formed when the metal ion is in large excess. Although the en-copolymer was the most effective functionalized one, higher maximum sorption capacities (Q(max)) were observed for the dien- and trien-copolymers, due to their abilities to form binuclear complexes. The enthalpy term has the greatest contribution to the total Gibbs energy change of reaction for the formation of mononuclear Cu(II) complexes (Delta G(aq)), while the solvation energy of the reaction has the greatest contribution in the formation of binuclear complexes. The results of the study indicate that small amines with the ability to form binuclear complex are the best choice for functionalization of the considered copolymer.

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.

The kinetics of Cr(VI) sorption by amino-functionalized poly(GMA-co-EGDMA) was investigated under non-competitive conditions. Competitive kinetics was studied from following multicomponent solutions: Cu(II) and Cr(VI); Cu(II), Co(II), Cd(II) and Ni(II): Cr(VI), Cu(II), Co(II) and Cd(II) solutions.

AB  - Four samples of macroporous crossliaked poly(glycidyl methacry late-co-ethy lene glycol dimethacrylate), poly(GMA-co-EGDMA), were synthesized by suspension copolymerization and functionalized by ring-opening reaction of the pendant epoxy groups wich etylone dramine and diethylene tiamine. Initial poly(GMA-co-EGDMA), as well as amino-functionalized samples poly(GMA-co-EGDMA)-en and poly(GMA-co-EGDMA)-deta, were characterized by FT-IR spectroscopy and elemental analysis. The sorption of Cu(lI) ions under static conditions on amino-functionalized samples was very rapid, with t1/2 value (time required to reach 50%6 of the total sorption capacity) beyond 1 min. The uptake of Ag(I) and Ni(II) ions on poly(GMA-co-EGDMA)-deta was also rather fast, with Lug of'1 and 2 minutes, respectively. Macroporous crosslinked poly (GMA-co-EGDMA)-deta showed considerably lower affinity for Co(II) ions, with t1/2 value of 13.8 min. The maximum sorption capacities of poly (GMA-co-EGDMA)-deta under non-competitive conditions at pH 5 were 2.41 mmol/g for Cu(II), 1.88 mmol/g for Co(II). 1.81 mmol/g for Ni(II) and 0.80 mmol/g for Cd(II) ions. The selectivity of poly(GMA-co-EGDMA)-deta towards Cu(II), Co(II), Cd(II) and Ni(II) investigated under competitive conditions was pH dependent. While at pH = I poly(GMA-co-EGDMA)-deta showed somewhat higher uptake for Cd(II) over other ions, at pH 5 the selectivity for Cu(II) over Ni(II) and Co(II) was 4 : 1, and over Cd(II) was 1.6 : 1. The uptakes of N(II) and Co(II) ions stayed almost the same in the whole pH range, i.e. around 0.20 mmol/g. The two parameters mass transter Thomas model was found to be suitable for describing data obtained from the column experiments carried out with single-component Cu(ll) solution and multi-component Cu(II), NI(II), Co(II) and Cd(II) solution. The possibility ol metal recovery and repeated use of the chelating copolymer was tested in several sorption/desorption cycles. Regeneration experiments performed with 0,1 and 1 M H2SO4, showed Cu(II) capacity loss of 50 % in first sorption/desorption cycle. The sorption capacity increased when additional neutralization with 0.1 and I M NaOH was performed after each sorption/desorption cycle.

While at pH = I poly(GMA-co-EGDMA)-deta showed somewhat higher uptake for Cd(II) over other ions, at pH 5 the selectivity for Cu(II) over Ni(II) and Co(II) was 4 : 1, and over Cd(II) was 1.6 : 1. The uptakes of N(II) and Co(II) ions stayed almost the same in the whole pH range, i.e. around 0.20 mmol/g. The two parameters mass transter Thomas model was found to be suitable for describing data obtained from the column experiments carried out with single-component Cu(ll) solution and multi-component Cu(II), NI(II), Co(II) and Cd(II) solution. The possibility ol metal recovery and repeated use of the chelating copolymer was tested in several sorption/desorption cycles. Regeneration experiments performed with 0,1 and 1 M H2SO4, showed Cu(II) capacity loss of 50 % in first sorption/desorption cycle. The sorption capacity increased when additional neutralization with 0.1 and I M NaOH was performed after each sorption/desorption cycle.",
