The adsorption of bentonite for Cs+ was studied by batch technique under ambient conditions.The different concentra-tions of Cs+ ,solid-to-liquid ratio and pH value on the sorption to bentonite was examined.The adsorption characteristics of Cs+by Bentonite were analyzed by FTIR,SEM,EDX and XRD.The results show that the adsorption percentage of bentonite to Cae-sium decreases from 94.17% to 47.09%,but the adsorptive capacity increases from 8.71 mg/g to 21.79 mg/g when the initial Cs+ concentration increases from 100 mg/L to 500 mg/L.The adso...
