Abstract

In the present study, a new technique to synthesize composites of poly(methyl methacrylate) cerium molybdate (PMMA–CeMoO4) is reported. The study concerns the characterization of poly(methyl methacrylate; PMMA) and PMMA–CeMoO4 nanocomposites are also discussed. The physical properties of the material were described using TGA–DTA, FTIR, X-ray, TEM, and SEM studies. The adsorption efficiency towards heavy metal ions was determined by distribution studies and material was found to be highly selective for lead, a heavy toxic metal ion, indicating the utility of the synthesized material for the removal of this ion from the waste stream. The material was used as electroactive component for the construction of an ion-selective membrane electrode. The membrane electrode was mechanically stable, having wide dynamic range, with quick response time and could be operated for at least 5 months without any considerable divergence in the potential response characteristics. The electrode was successfully used as indicator electrode in complexation titrations. © 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013
