FIELD: chemistry.
SUBSTANCE: in the method a dry anion-exchange membrane is exposed at room temperature in a 1-50% water solution of hydrogen peroxide for 1-14 days.
EFFECT: facilitation of the transfer of anions, containing compounds of hexavalent chromium, through the processed in such a way membrane under an influence of electric current, increase of the membrane service term with the preservation of its mechanical strength.
