Abstract
A new class of hybrid nanocomposite, poly(aniline-co-o-toluidine)(PANI-Co-OT) tungstomolybdate (TM) was prepared by sol gel method. The physico-chemical characterization was carried out by Scanning Electron Microscopy (SEM), X-ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), Ultra Violet Spectroscopy (UV-vis) and simultaneous Thermogravimetric Analysis (TGA) studies. The ion-exchange capacity, distribution studies were also carried out to understand the ion-exchange capabilities. It is highly semiconducting nature in the range of 1.6155 x 10(-1)-3.0786 x 10(-1) S/cm. Based on distribution studies, composite was found highly selective for Pb(II) heavy metal ions. Ion-selective membrane electrode was designed for the determination of Pb(II) ions in solutions. The analytical utility of this membrane was established by employing it as an indicator electrode.
