Radiation effects on silica-titania gel

Laboratory experiments were performed on the sorption of cesium on gamma-ir radiated silica-titania gel. The detrimental effects of absorbed dose on th e affinity of the sorbent towards cesium was discussed. Data obtained from sorption studies were fit into heterogeneity based Freundlich isotherm. The empirical parameters, thus obtained were used to arrive at the site distri bution function. The potential of site distribution function in foreseeing, the reusability and long-term residence of radionuclides in the sorbent ha s been highlighted.
