Abstract
- Abstract: PVC supported membranes of polyaniline–titanium(IV)phosphate (PANI–TiP) cation exchange nanocomposite were prepared by solution casting method in different stoichiometric ratios of PVC and PANI–TiP. The structure and morphology of the prepared membrane were ascertained by FTIR, SEM and TGA–DTA. The membrane having a composition 1:1 (PVC:PANI–TiP) shows best results for electrical conductivity, water content, porosity, thickness and swelling. The Pb(II) selective electrode was developed by using this membrane for the determination of lead in solutions. The membrane electrode was mechanically stable, having wide dynamic range, with quick response time and could be operated for at least 5 months. [Copyright &y& Elsevier]
