A functionalized hydrogel composed of 2-(hydroxyethyl) methacrylate (HEMA) and acrylamide (AAm) was synthesized by amination and saponification reactions, respectively, and its functionality was examined for the elimination of copper(II) ions. The maximum adsorption capacity for copper(II) ions was 0.617 mmol g(-1) before saponification, whereas it was 1.2225 mmol g(-1) after saponification. The adsorption data was analyzed with pseudo-first-order (r(2) =0.8867), intra-particle diffusion (r(2) =0.9453), Elovich (r(2) =0.9489) and pseudo-second-order(r(2) =0.9999) kinetic models. Based on the adsorption equilibrium experimental data Freundlich(r(2) =0.9964), Langmuir(r(2) =0.998) and Dubinin-Radushkevich (D-R) (r(2) =0.9960) adsorption isotherms provided good fits for all of experimental results. Finally, the datas of kinetic experiments obtained in this study showed the applicability of the functionalized gel for Copper(II) ion removal.
