The terpolymeric resins abbreviated as PAQM-I, PAQM-II and PAQM-III was synthesized by polycondensation of p-Hydroxyacetophenone, Quinhydrone and Melamine in 1:1:1, 1:3:1 and 1:4:2 molar proportions respectively, in presence of Poly-Phosphoric acid (PPA). The resins were characterized by various physico-chemical methods such as elemental analysis, IR, 1H-NMR, UV-Vis and non-aqueous conductometric titrations. Chelating ion- exchange properties of PAQM-I, PAQM-II and PAQM-III terpolymer were studied for Cu2+, Mg2+, Pb2+ and Bi3+ by batch equilibrium method. PAQM resins are more selective Cu2+> Mg2+> Pb2+. However, with varying pH the ion exchange selectivity was found to change with varying pH. Therefore the resin can be used for selective separation of metals at particular pH.
