SORPTION EXTRACTION OF Сu2+, Co2+, Ni2+ AND Pb2+ FROM AQUEOUS SOLUTIONS BY TETRAZOLE POLYMERS BASED ON COMMERCIAL ACRYLONITRILE COPOLYMER
Abstract
The sorption activity of tetrazole-based polymers prepared from commercial copolymer of acrylonitrile, methyl acrylate and 2-acrylamido-2-methylpropanesulfonic acid was studied in relation to Сu2+, Co2+, Ni2+ and Pb2+ in diluted aqueous solutions. It was found that the sorption capacity grew with increasing the tetrazolation ratio and the specific surface area of polymer. The possibility of selective sorption of Cu2+ in the presence of Co2+ was shown. The recovery of the sorbent after ion exchange sorption was achieved by treating with dilute hydrochloric acid.
