摘要：
Nitrogen-containing polymer sorbents for extracting iron from the brine used in the electrolytic production of caustic soda and chlorine have been synthesized. These sorbents were synthesized by chemically treating a mixture of perchlorovinyl resin, polyvinyl chloride and vinyl chloride/vinyl acetate copolymers with acyclic and cyclic di- and polyamines at a temperature of 60-160 degree C for 2 to 8 hours in the presence of solvents. Tests of these sorbents showed a high sorption capacity with respect to iron and a sorption efficiency superior to that of methyl cellulose.
