The adsorption behavior of cesium on silica gel.
Cesium adsorption on silica gel has been studied as a function of different particle sizes (15, 40 and 63 microm), cation concentrations and temperatures. The adsorption behavior of cesium was evaluated by using the radiotracer method. The temperatures chosen for the study were 25 degrees C, 40 degrees C, and 60 degrees C. Cesium concentrations were ranged between 1 x 10(-6) - 1 x 10(-3)M. The data were fitted to both Freundlich and Dubinin-Radushkevich isoterms. The thermodynamic parameters calculated from the adsorption results were used to explain the mechanism of the adsorption.
