Abstract

Tetravalent metal acid salts based cation exchanger; tin zirconium phosphate was synthesized by sol-gel process. The ion exchange capacity, chemical stability, effect of temperature and pH titration studies were carried out to understand the ion exchange capability. The study of effect of temperature on ion exchange capacity of this material indicated the pronounced ion exchange capacity even at elevated temperature. The physico-chemical characterization was studied by elemental analysis, XRD, FTIR and TGA. The thermal analysis depicted the enhanced thermal stability of this material. The X-ray diffraction study showed that the material formed is semicrystalline in nature. The distribution studies of different metal ions on the exchanger were performed in different solvent systems and it was found to be selective for PbII and CuII ions. The presence of protons makes the TMA salt, a potential candidate for solid state protonic conduction. In the present endeavour, the proton conduction behaviour of these materials has been studied by measuring specific conductance (S) at different temperatures in the range 30–80°C using Solatron (1255B FRA FI1287 Electrochemical Phase) impedance analyzer. The specific conductance values for the single salts counter parts (tin phosphate and zirconium phosphate) have been compared.
