Abstract
The preparation and electrochemical properties of Pb2+ ion selective m embrane sensor have: been studied using zirconium tungstophosphate (ZW P) cation exchanger as an electroactive material and araldite as binde r. The detection limit of this membrane for Pb2+ ions is 2.51 x 10(-4) M with a slope of 38 mV/decade of concentration. The working pH range for the membrane is 3 to 6 and its response time is <10s to all conce ntrations.
