EDTA-Zr(IV) iodate was prepared via the incorporation of-aqueous solution of EDTA into the inorganic precipitate of Zr(IV) iodate. Distribution coefficient values for different metals showed that EDTA-Zr(IV) iodate had the highest adsorption capacity for Pb(II). The practical applicability of EDTA-Zr(IV) iodate was explored by separating Pb(II) metal from a synthetic mixture of metal ions. Dependence of adsorption on contact time, pH of the solution, exchanger dose and temperature was studied to achieve the optimum conditions. Kinetic studies showed better applicability for pseudo-second-order model. Thermodynamic parameters viz. - entropy change, enthalpy change and Gibb's free energy change were also calculated.
