Abstract
Recovery of strontium-90 with barium manganite from fresh waters (natu ral fresh waters of open basins) can be increased by adding agents tha t contain sulfate ions and thus modify the sorbent and chemically bind the sorbate. The treatment results in a heterogeneous anion-exchange transformation of barium manganite into barium sulfate-manganese dioxi de and in simultaneous adsorptive coprecipitation of strontium sulfate (microcomponent).
