A study was carried out on the adsorption of zinc ions by ion-exchange materials derived from fibrous copolymers of acrylonitrile (AN) with 2-acrylamide-2-methylpropanesulfonic acid (AMPS), acrylic acid (AA), or itaconic acid (ItA) as the ionogenic component. The adsorption activity of materials derived from poly[AN-co-AMPS] containing sulfo groups is somewhat reminiscent of the behavior of carboxyl ion-exchange resins. The amount of zinc adsorbed by materials derived from poly[AN-co-AMPS] may exceed the static exchange capacity (SEC) for sulfo groups. It was proposed that the amide groups affect the adsorption behavior of ion exchangers derived from poly[AN-co-AMPS].
