Abstract
А new polyethyleneimine sulfur-containig exchanger network structure with static exchange capacity of 0.1 N solution of HCl 4.7 mEq/g was obtained by polycondensation of glycidyl methacrylate, methyl methacrylate and phosphoric acid. Sorption of copper (II) and zinc (II) ions was studied and investigated in static conditions from model solutions of sulfates of copper and zinc, in dependence on their concentration and pH, as well as their contact time with the ion-exchanger. Found that the magnitude of the sorption capacity of the ion exchanger for ions of copper (II) at pH 3.6 CuSO4 solution is 4.03 mg / g. It has been established that zinc ion (II) is absorbed best by the sorbent at pH 4.06. In these conditions the sorption capacity of the sorbent for copper ions (II) and zinc (II) respectively equal to 0.8225mmol / g (Cu) and 0.8305mmol / g (Zn). The sorption ability new sulfur-containing ionite with respect to copper ions (II) and zinc (II) is significantly higher than for industrial ionite of KU-2x8.
