| Abstract: | Amorphous titanium phosphate, an inorganic ion exchanger of the class of tetravalent metal acid salt, has been synthesized by sol-gel method, and characterized for elemental analysis (ICP-AES), spectral analysis (FT-IR), thermal analysis (TGA, DTA, DSC) and X-ray diffraction studies. Chemical resistivity of the material has been assessed in various media, i.e., acids, bases and organic solvents. The Na⁺ ion exchange capacity has been deter-mined and effect of heating on the ion exchange capacity has been studied. The sorption/ion exchange behaviour of the exchanger towards Cu(II), Mn(II), Ni(II) and Zn(II) has been studied at dif-ferent temperatures (313 K, 323 K and 333 K). Kinetic and ther-modynamic parameters have been evaluated and adsorption iso-therms have been studied. Based on the above studies the selectiv-ity order is found to be: Mn(II) > Ni(II) > Cu(II) > Zn(II). |
