Abstract
Hydrated cerium (IV) dioxide has been synthesized by adding excess cerium sulphate to 4M ammonia solution at 250C and pH=12.5 with constant stirring. The properties of the compound were investigated by means of infrared and thermogravimetric techniques. The effect of temperature and pH on the adsorption of Ba and Sr ions and also the distribution coefficients of Cs and Eu at various pH values on cerium (IV) dioxide were considered. The distribution coefficient results showed that with the increase of pH of the media, the amount of adsorption of Ba and Sr cations on the surface of cerium (IV) dioxide increases, and this is due to their amphoteric nature of this oxide.
