Abstract: Here the elution, retention and separation of some heavy metals on the column of synthesized zeolitic material have been investigated. The zeolitic material was synthesized from fly ash by hydrothermal treatment with NaOH for 24 hours. The ion exchange capacity elution behavior and distribution studies were carried out to determine the preliminary ion exchange properties of the material. The elution behavior of Mn2+, Fe3+, Cd2+, Cr3+, Pb2+, Zn2+, Ni2+, As3+, Mo6+ and Hg2+ were attempted on zeolitic material. On the basis of distribution coefficients studies some binary separations of heavy metal ions such as Bi3+-Ni2+, Bi3+-Cr3+, Mo2+–Cr3+, Sb2+–Cd2+, and Pb2+-Cd2+ were achieved on the column of zeolitic ion exchange material. The separation and estimation of Fe3+, Cr3+, Pb2+, Sb3+ and Ni2+ from the different water samples were also attempted on zeolitic material.
