Abstract In this study, Nickel Hexacyanoferrate-Clinoptilolite composite (NiHCF-Clino) was prepared and used as an ion exchanger for the removal of cesium from aqueous solution. The effect of various parameter like the pH, contact time, temperature and initial concentration of cesium on adsorption efficiencies of NiHCF-Clino has been studied systematically by batch experiments. The results show that maximum adsorption capacity of cesium onto NiHCFClino adsorbent was found to be 108.69 mg.g-1. Then, the cesium-loaded adsorbents were heated at different temperature and the leach test carried out on all the heat-treated samples. Leaching results show that immobilization ability of ion cesium in the heated-treated materials increased as the treatment temperature was increased.
