INTERACTIONS OF THE WATER-SOLUBLE POLY(N-MALEYL GLYCINE-CO-ACRYLIC ACID) AS POLYCHELATOGEN WITH METAL-IONS IN AQUEOUS-SOLUTION

The metal complexation of water-soluble poly(N-maleyl glycine-co-acryl ic acid) with Co(II), Zn(II), NI(II), Cu(II), Fe(II), Cd(II, Pb(II), a nd Sr(II) ions was investigated in aqueous phase using the Liquid-Phas e Polymer-Based Retention (LPR) technique. The water-soluble P(MG-co-A A) copolymer was shown to be useful for the retention of different ino rganic ions in conjunction with membrane filtration and their separati on from ions not bound to the polymeric reagent. At higher pH, the wat er-soluble copolymer can be applied to the separation and preconcentra tion of many metal ions. Maximum capacity values of the copolymer for copper(II) were determined at different pH. Viscometric measure-ments of the copolymers were performed in the presence of the nine metal ion s at different pH values.
