METHOD OF PRODUCING COPPER (+2) HYDROXOCHROMATES

摘要

FIELD: chemistry.SUBSTANCE: invention can be used in inorganic chemistry. The method of producing copper (+2) hydroxochromates involves preparing a reactive aqueous solution containing chromium (+6) and copper (+2), forming a copper (+2) hydroxochromate precipitate and separating said precipitate from the solution. The chromium (+6) source used is a liquid electroplating waste - a spent solution containing chromium (+6), and the copper (+2) source used is a liquid radioelectronic production waste - a spent solution from etching printed-circuit boards and/or a spent solution from copper plating printed-circuit boards.EFFECT: invention enables to recycle liquid electroplating wastes and printed-circuit board wastes.13 cl, 7 ex
