Abstract

The paper analyzes polymer fibrous ion-exchange materials on the basis of polyacrylonitrile matrix released as KN-1 cation exchanger and AS-1 and AN-1 anion exchangers. The purpose is to study the sorption properties of the specified materials in relation to multicomponent salt solutions of heavy metals. According to obtained results, the exchange processes are characterized by high speed, and materials - by high exchange capacity. The cascade filtration purifies heavily polluted industrial waste waters to the levels of 10-3 mg/l of Pb (II), Zn(II), CD (II), Cu(II), Mo(VI), W(VI) thus fully satisfying hygienic requirements. The advantages of the studied materials include low flow resistance, a possibility of repeated regeneration (with acid and alkali) with desorption of valuable components and creation of waste-free or low-waste technologies on their basis.
