ABSTRACT:
The objectionable hypochlorite values, ClO.sup.- ions, contained in a solution of an alkali metal perchlorate produced by the electrolysis of an aqueous solution of the corresponding chlorate of the alkali metal, are effectively destroyed (consumed) without adversely affecting the valence state of the hexavalent chromium values also contained therein, by intimately contacting such perchlorate solution with an effective amount of hydrogen peroxide such that the molar ratio available hydrogen peroxide/hypochlorites is at least one.
