Abstract

Adsorption of cesium (Cs+), strontium (Sr2+), and europium (Eu3+) onto stannic silico vanadate as ion exchange material, and the effects of experimental conditions on adsorption were considered. The material were characterized by X-ray diffractometer system (XRD), scanning electron microscopy (SEM), X-ray fluorescence spectrometry (XRF), infrared (IR), and thermal analysis (TGA and DTA). The selectivity coefficients for different cations determined by mixed solution method were found to be less than unity. The thermodynamic parameters such as ΔG*, ΔS*, and ΔH* have also been calculated for the adsorption of Cs+, Sr2+, and Eu3+ onto stanic silicovanadate, showing that the overall adsorption process is spontaneous and endothermic.
