The new additive for extraction of cations of heavy metals from acid solutions containing strong oxidizers, by their transfer in insoluble substances with liberation of equivalent quantity of cations of hydrogen is offered. The greatest degree of extraction is observed for copper cations. The additive allows to reduce essentially concentration of copper substances in acid solutions of pickling of copper, and also in the acid solutions containing hexavalent chrome, for example, in electrolyte of chromium plating.
