Abstract

Sorption of copper ions(II), nickel(II), cobalt(II) and zinc(II) from individual solutions and in
their joint presence at the N-(2-carboxyethyl)aminopolysteren (sorbent 1) and
N-(2-carboxyethyl)polyallylamine (sorbent 2). Established a significant mutual influence of these ions on
their distribution coefficients for both sorbents. Determined conditional stability constants of surface
complexes and the exchange capacity of the ions studied. Assumptions about the possible causes of the
mutual influence of ions during sorption
