Abstract

Five bentonite samples of different compositions and geneses were saturated with Cs and Sr in the static regime. Desorption is examined during the filtration of distilled water through saturated samples. Both elements are firmly retained to most of the bentonite samples. The Cs and Sr desorption values were 12–20%, and 2.5–23%, respectively. Structural changes in the clay fraction of bentonites resulted from the sorption–desorption of Cs and Sr were studied by the method of X-ray diffraction.
