FIELD: chemistry.
SUBSTANCE: method for rhenium isolation implies passing rhenium-containg solution through strongly-basic anion-exchange resin and elution of adsorbed rhenium with high-concentration aqueous solution of hydrochloric acid. Anion-exchange resin is treated with an oxidising aqueous solution, where hydrogen peroxide is used as an oxidiser.
EFFECT: increase in ion exchanger service life.
