Polyaniline Sn(IV) tungstomolybdate nanocomposite (PSTM) was synthesized by sol–gel method. Thephysico-chemical properties of PSTM were studied using FTIR, TGA, XRD, SEM, and TEM. The materialwas successfully used for the removal of Pb2+. Batch experiments were performed as a function of variousexperimental parameters such as effect of pH (2–8), contact time (5–60 min), initial Pb2+ concentration(10–30 mg L 1) and temperature (20–50 8C). The removal rate of Pb2+ using PSTM was fast andequilibrium established within 50 min. Kinetic studies showed better applicability for pseudo-firstordermodel. The values of thermodynamic parameters (DG8, DH8 and DS8) were also computed.

A composite material polyaniline-Zr(IV) phosphoborate (PZPB) was synthesized via sol-gel method by the combination of Zr(IV) phosphoborate and polyaniline. The PZPB composite material was characterized by various analytical techniques. The PZPB composite material was found to be selective for Hg2+ metal ion due to the high distribution coefficient values for Hg2+ metal ion in all mediums. The PZPB composite material was used for Hg2+ removal under different experimental conditions. The antibacterial activity of PZPB composite material was also studied against E. coli.
