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.
