摘要：

Polyurethane-cerium(IV) phosphate composite cation exchange membranes were prepared by casting method in different stoicheometric ratios of polyurethane and cerium(IV) phosphate. structure and morphology of the prepared membranes were ascertained by FTIR, SEM, TGA and membrane having composition 1:2 (PU: cerium(IV) phosphate) shows best results for capacity, water content, porosity, thickness and swelling. The Cu(II) selective electrode was using this membrane for the determination of Cu(II) in solutions. The accuracy of the procedure has tested on drinking water samples spiked with known amounts of Cu(II) and results were those generated by Atomic Absorption Spectrophotometer.
