Adsorption of Some Hazardous Radionuclides on Cerium(IV) Antimonate
- 1. Atomic Energy Authority , Hot Labs. Centre, Cairo, (Egypt)
Description
Cerium(IV) antimonate had been prepared by the dropwise addition of 0.6 M antimony pentachloride and 0.6 M cerium ammonium nitrate solutions by a molar radio of Ce/Sb 0.75. Exchange isotherms for H+/Co2+ , H+/Cs+, H+/Zn2+ , H+/Sr2+ and H+/Eu3+ have been determined at 25, 40 and 60 degree. Besides it was proved that europium is physically adsorbed while zinc, strontium, cobalt and cesium are chemically adsorbed. Moreover, the heat of adsorption of zinc, strontium, cobalt and cesium on cerium(IV) antimonate had been calculated and indicated that cerium(IV) antimonate is of endothermic behaviour towards these ions. Also the distribution coefficients of these ions were determined and it was found that the selectivity in the order: Eu3+ >Sr2+ > Cs+>Na+
