A lead (II) ion selective sensor has been facilely fabricated from Styrene - Acrylonitrile (SA) copolymer as a neutral carrier, sodium tetra phenyl borate (NaTPB) as an anionic excluder and tri butyl phosphate (TBP) as a plasticizing solvent mediator. Fabricated sensor, over a concentration range of 1x10-5-1x10-1 mol L-1 revealed a best Nernstian response for Pb (II) ions with a slope of 39.60 mV/decade. Potentiometric selectivity coefficient values as determined by Fix Interference Method (FIM) and Match Potential Method (MPM) indicated that the electrode has good selectivity of Pb2+ ion over other heavy metal ions. The performance of proposed sensor in non aqueous mixtures up to 20 % (v/v) ethanol was satisfactory. The effect of surfactant and detergent on the working of Pb2+ ion selective electrode was also studied. The electrode can be used for the determination of lead ion pollution in waste water sample.
