Five bentonites samples of the different composition were saturated with Cs and Sr under the static conditions. The desorption were examined under the filtration of distilled water through the saturated bentonite samples. Most of the studed bentonites effectively retarded both Cs and Sr. Cs desorption values were 12-20%, and Sr desorption - 2,5-23%. Structural alterations took place in the clay fraction of bentonites as a result of the sorption-desorption processes were studied by X-ray diffraction.
