| Abstract: | Amorphous zirconium phosphate (ZP), an inorganic ion exchanger of the class of tetravalent metal acid (TMA) salt, has
been synthesized by sol-gel method, and characterized by elemental analysis (ICP-AES), thermal analysis (TGA, DSC), FT-IR
and X-ray diffraction studies. Sorption/ion exchange behavior of metal ions [Pb(II), Bi(III) and Th(IV)] towards ZP has been
studied varying temperature, kinetic (over all rate constant k2 and equilibrium constant kc,) and thermodynamic parameters
(standard free energy ΔG°, enthalpy ΔH°, and entropy ΔS°) evaluated and adsorption isotherms (Langmuir and Fruendlich)
studied. Sorption of metal ions follows the order Pb(II) > Bi(III) > Th(IV). |
