This paper deals with adsorption regularities and mechanisms of nonradioactive Cs(I) Sr(II) analogs on bentonites different chemical mineral composition from solutions Cs Sr nitrates pH 3, 7, 10 units at constant ionic strength. The were taken the deposits Taganskoe (T), Dash-Salakhlinskoe (DS), Zyryanskoe (Z), 10th Khutor (10H). bentonite aqueous suspensions, T DS, exceeded 9 units. A less alk...
