Аннотация: the process of sorption of Mn2 +and V4 +cations by bentonite of the Tagan deposit studied depending on various factors (T, oC; τ, min; S: L ratio; CMnand CV, mg/l). It was found that bentonite exhibits sorption properties with respect to the studied cations in a wide range of pH values (from 1 to 10). The highest degree of their sorption is achieved at the consumption of bentonite 1.5 g per 100 mass. p.of metal-containing solution. The influence of the nature of the cation on the sorption capacity of Tagan bentonite was established. The most intense increase in the degree of sorption of manganese (II) occurs in 15 min with an increase in temperature to 35оС.The highest degree of sorption of V4 +cations is achieved in 60 min at 25°C in weakly concentrated vanadium-containing solutions (50 mg/l V4 +). Bentonite from the Tagandeposit exhibits a lower sorption capacity with respect to V4 +cations as compared to Mn2 +cations, which is due to the nature of the cation.
