Cs SORPTION FROM AQUEOUS SOLUTIONS ON NATURE BENTONITES

Sorption studies of 137Cs on natural bentonites Tagansky, Dashkovsky, Zyryanovsky deposits and the 10th Khakassia field, both from neutral aqueous solutions and solutions with elevated saline background were performed. All clay samples studied revealed high sorption ability with respect to 137Cs, namely more than 80%. It was noted the negative effect of strong salt background - a decrease in sorption by 15-20%, while the presence of the only 1 g/l NaNO3 in solution slightly increases the sorption index.
