SYNTHESIS AND STUDY OF NEW CHELATING POLYMER SORBENTS
Keywords:
chelating ion exchangers, polyelectrolyte, chelating agents, sorption, heavy metals, ion exchangeAbstract
In the laboratory synthesized a new chelating ion-exchange materials based on ternary copolymer of glycidylmethacrylate (GMA), styrene (St), acrylonitrile (APC) and the chelating agent oxyethylidendiphosphonic acid (HEDP). Optimal conditions of synthesis and the physico-chemical properties of the ion exchanger for practical use. The proposed method of synthesis provides for the production of new complexing polyelectrolytes based on copolymers of epoxyacrylates and some complex on swith improved physical and chemical characteristics for practical application in the field of non-ferrous metallurgy.
