Abstract
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.
