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 RedlichPeterson isotherm models. The kinetics data were studied using pseudo-first-order, pseudo-secondorder, 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  - 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  - 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  - 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.

AB  - A novel magnetic polymer/bentonite composite was prepared by suspension copolymerization of glycidyl methacrylate and ethylene glycol dimethacrylate in the presence of magnetic bentonite (MB-PGME) and functionalized with ethylene diamine and hexamethylene diamine (MB-PGME-ED and MB-PGME-HD). The obtained samples were characterized in terms of structure as well as thermal, magnetic and morphological properties. The sorption of rhenium (Re) and tungsten (W) from aqueous solution onto MB-PGME-ED and MB-PGME-HD was investigated considering their contact time and different initial ion concentration, giving possibility for usage of these composites as commercial sorbents. The sorption system follows the pseudo-second order and intraparticle diffusion kinetic models. The results indicated a better fit with the Freundlich isotherm model.

AB  - Chelating copolymers show high efficiency in sorption of different ionic species in aqueous solutions. The specific structure of chelating macroporous copolymers made by the porous matrix and functional groups with the heteroatoms N, O, S and P; allows them to establish various types of interactions with ions and molecules from the immediate surroundings. Furthermore amino-functionalized macroporous copolymer of glycidyl methacrylate and ethylene glycol dimethacrylate poli (GME) has a high capacity and good selectivity for the precious and heavy metal ions over alkali and alkaline earth metals. In this study, aminofunctionalized magnetic macroporous m-poli (GME)-deta was fully characterized in terms of its structural properties using: FTIR, SEM/EDX and XRD analysis. The macroporous copolymer was further used to investigate the sorption of pentavalent vanadium oxyanions from diluted aqueous solutions (Ci = 25 ppm) in a batch system, at room temperature (298 K). The oxyanion concentrations in a solution was determined by inductively coupled plasma atomic emission spectroscopy (ICP-AES).The pseudo-first-order (PFO), pseudo-second-order (PSO), Elovich and intra-particle diffusion (IPD) models were used to analyze the kinetic data. The study has shown that sorption is rapid, i.e. the half-sorption time, t1/2 is approximately 1 minute. Initially, it has been the dominant sorption on the surface of the particles and the process has been best described by the PSO model (which takes into account the binding between sorbate and sorbent). The moment it has reached saturation of the sorbents surface active sites, sorption rate decreases significantly because the sorption has been limited by the rate of diffusion through the pores and kinetic has been controlled by the intraparticle diffusion process. IPD kinetic model showed a good fit to the experimental data with R2 values > 0.95.

AB  - Vanadium and its compounds have multiple applications in industry, such as in alloys to increase strength and as a catalyst. Vanadium(V) is the dominant form in the aquatic environment and also, it is the most hazardous product which can cause an environmental problem due to its high solubility and toxicity. The aim of this study was to investigate the possible use of a novel magnetic polymer/bentonite composite prepared by suspension copolymerization of glycidy. methacrylate (GMA) and ethylene alyco. dimethacrylate (EGDMA) and functionalize with ethylene diamine and hexamethylene diamine (MB-PSME-ED and MB-PGME-HD), for V(V) sorption from

aqueous solution. The influence of contact time on V(V) sorption onto MB-PGME-ED and MB-PGME-HD was investigated. All sorption experiments were performed in batch static conditions, at pH 7.6 and room temperature (298 K). Maximum sorption capacities, Qmax, were 2.47 mg/g and 1.94 mg/g for MB-PGME-ED and MB-PGME-HD, respectively. Surface-reaction (pseudo-first order, pseudo-second order and Elovich) and particle diffusion based (intra-particle diffusion, liquid film diffusivity model, Bangham, Boyd and McKay's) kinetic models were used for analysis of V(V) sorption kinetic data. Both sorbents obeyed the pseudo-second order kinetic model, with evident influence of pore diffusion. Desorption experiments of V(V) loaded MB-PGME-ED and MB-PGME HD performed with 0.1 M NaOH and 0.1 M HNO3 showed that NaCH is a better stripping agent for V(V) ion within both samples.

AB  - Arsenic is a metalloid, which occurs in nature in various forms, but in
natural waters mainly in the form of pentavalent oxyanion of arsenate As(V) and
trivalent arsenite As(III), which dominates under anaerobic conditions. Arsenic
water pollution is a serious problem due to its pronounced negative impact on
human health. This paper describes the kinetic and equilibrium studies of the
sorption mechanism of oxyanion As(V) in monocomponent aqueous solutions on
a silanized magnetic amino-functionalized copolymer of glycidyl methacrylate
and ethylene glycol dimethacrylate m-Si-PGME-deta. It has been shown that the
sorption of As(V) on m-Si-PGME-deta is a rapid process, initially controlled by
ion diffusion rate through solution. After achieving the saturation of the sorbent
surface, the sorption rate decreases, because the sorption rate determines
the process of intraparticle pore diffusion. The maximum sorption capacity is
5.61 μmolˑg-1.
AB  - Arsen je metaloid, koji pripada IV periodi i 15. grupi periodnog sistema, široko rasprostranjen
u Zemljinoj kori u obliku različitih vrsta minerala. U vodenoj sredini pretežno se nalazi u obliku
petovalentnog oksianjona аrsenаta As(V) i trovalentnog аrsenita As(III) koji dominira u anaerobnim
uslovima. Zаgаđenje vode аrsenom predstavlja ozbiljan problem zbog izraženog negаtivnog efekta
ovog elementa nа ljudsko zdrаvlje. Zbog toga su za uklanjanje arsena iz otpadnih voda razvijene
različite metode koje se uglavnom zasnivaju na flokulaciji, sorpciji ili membranskoj separaciji. U
ovom radu opisano je ispitivanje efikasnosti sorbenta na bazi silaniziranog magnetita i aminofunkcionalizovanog kopolimera glicidil metakrilata i etilen glikol dimetakrilata, m-Si-PGME-deta, za
uklanjanje petovalentnog oksianjona arsena iz vodenih rastvora. Mehanizam sorpcije oksianjona
As(V) na sorbentu m-Si-PGME-deta ispitan je praćenjem kinetičkih i ravnotežnih parametara u
monokomponentnim vodenim rastvorima. Kinetika sorpcije analizirana je primenom modela pseudoprvog i pseudo-drugog reda, Jelovičevog i modela unutarčestične difuzije (IPD). Ravnotežni podaci
analizirani su Lengmirovim, Frojndlihovim i Temkinovim modelima izotermi. Pokazalo se da je sorpcija
oksianjona As(V) na m-Si-PGME-deta brz proces koji je u početnoj fazi kontrolisan brzinom difuzije
jona u rastvoru, zbog čega i kinetika sorpcije u toj fazi odgovara modelu pseudo-drugog reda. Po
dostizanju saturacije površine sorbenta, dolazi do rapidnog opadanja brzine sorpcije jer postaje
dominantno vezivanje jona za aktivna mesta u unutrašnjosti sorbenta, kada proces unutarčestične
difuzije kroz pore sorbenta određuje brzinu vezivanja jona, što najbolje opisuje kinetički model

abstract = "Arsenic is a metalloid, which occurs in nature in various forms, but in
natural waters mainly in the form of pentavalent oxyanion of arsenate As(V) and
trivalent arsenite As(III), which dominates under anaerobic conditions. Arsenic
water pollution is a serious problem due to its pronounced negative impact on
human health. This paper describes the kinetic and equilibrium studies of the
sorption mechanism of oxyanion As(V) in monocomponent aqueous solutions on
a silanized magnetic amino-functionalized copolymer of glycidyl methacrylate
and ethylene glycol dimethacrylate m-Si-PGME-deta. It has been shown that the
sorption of As(V) on m-Si-PGME-deta is a rapid process, initially controlled by
ion diffusion rate through solution. After achieving the saturation of the sorbent
surface, the sorption rate decreases, because the sorption rate determines
the process of intraparticle pore diffusion. The maximum sorption capacity is
5.61 μmolˑg-1., Arsen je metaloid, koji pripada IV periodi i 15. grupi periodnog sistema, široko rasprostranjen
u Zemljinoj kori u obliku različitih vrsta minerala. U vodenoj sredini pretežno se nalazi u obliku
petovalentnog oksianjona аrsenаta As(V) i trovalentnog аrsenita As(III) koji dominira u anaerobnim
uslovima. Zаgаđenje vode аrsenom predstavlja ozbiljan problem zbog izraženog negаtivnog efekta
ovog elementa nа ljudsko zdrаvlje. Zbog toga su za uklanjanje arsena iz otpadnih voda razvijene
različite metode koje se uglavnom zasnivaju na flokulaciji, sorpciji ili membranskoj separaciji. U
ovom radu opisano je ispitivanje efikasnosti sorbenta na bazi silaniziranog magnetita i aminofunkcionalizovanog kopolimera glicidil metakrilata i etilen glikol dimetakrilata, m-Si-PGME-deta, za
uklanjanje petovalentnog oksianjona arsena iz vodenih rastvora. Mehanizam sorpcije oksianjona
As(V) na sorbentu m-Si-PGME-deta ispitan je praćenjem kinetičkih i ravnotežnih parametara u
monokomponentnim vodenim rastvorima. Kinetika sorpcije analizirana je primenom modela pseudoprvog i pseudo-drugog reda, Jelovičevog i modela unutarčestične difuzije (IPD). Ravnotežni podaci
analizirani su Lengmirovim, Frojndlihovim i Temkinovim modelima izotermi. Pokazalo se da je sorpcija
oksianjona As(V) na m-Si-PGME-deta brz proces koji je u početnoj fazi kontrolisan brzinom difuzije
jona u rastvoru, zbog čega i kinetika sorpcije u toj fazi odgovara modelu pseudo-drugog reda. Po
dostizanju saturacije površine sorbenta, dolazi do rapidnog opadanja brzine sorpcije jer postaje
dominantno vezivanje jona za aktivna mesta u unutrašnjosti sorbenta, kada proces unutarčestične
difuzije kroz pore sorbenta određuje brzinu vezivanja jona, što najbolje opisuje kinetički model
IPD. Ispitivanje ravnotežnih parametara pokazuje najbolje slaganje Frojndlihovog modela sa
eksperimentalnim podacima, iz čega se može zaključiti da na površini sorbenta postoje aktivna mesta
sa različitim energijama vezivanja jona. Maksimalan kapacitet sorpcije iznosi 5.61 µmolˑg-1.",
