The ability of cross-linked pyridylethylpolyethylenimine with the degree of substitution of 0.32 to sorb Cu2+, Ni2+, Co2+, Zn2+, Cd2+, Mn2+, and Pb 2+ ions present simultaneously in solution was evaluated. In an ammonium acetate sorption system (pH 3.5-4.0), the sorbent selectively interacts with Cu(II) ions Доп.точки доступа: Lakiza, N. V.; Tissen, O. I.; Neudachina, L.K.; Ezhikova, M. A.; Kodess, M.
