Fabrication of Gelatin-Zr (IV) Phosphate and Alginate-Zr (IV) Phosphate Nanocomposite Based Ion Selective Membrane Electrode

Abstract

Gelatin- Zr (IV) phosphate nanocomposite (GT@ZPNC) and alginate- Zr (IV) phosphate nanocomposite (AG@ZPNC) ion exchangers has been prepared by sol-gel method. The nanocomposites are characterised by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The SEM results of GT@ZPNC and AG@ZPNC confirmed that after the binding of polymer matrix to inorganic part, morphology was completely reformed. TEM results confirmed the synthesised materials were nanocomposite in nature. The GT@ZPNC and AG@ZPNC ion exchangers have been explored to fabricate ion selective electrode for the detection of Cd (II) and Al (III) metal ions. Both ion selective membrane electrodes show wide working concentration and pH range with good response time.

Sol–gel synthesis of polyacrylamide-stannic arsenate nanocomposite ion exchanger: binary separations and enhanced photo-catalytic activity

“…PA/SANC ion exchanger was synthesized in two phases [38,39]. In first, 0.2 M stannous chloride and 0.4 M sodium arsenate (2:1) were mixed with constant stirring at room temperature.…”
