ABSTRACT:
The objectionable hypochlorite values, ClO.sup.- ions, contained in a solution of an alkali metal chlorate produced by the electrolysis of an aqueous solution of the corresponding chloride of the alkali metal, are effectively destroyed (consumed) without adversely affecting the valence state of the hexavalant chromium values also contained therein, by intimately contacting such chlorate solution with an effective amount of hydrogen peroxide such that the molar ratio hydrogen peroxide/hypochlorites is at least one and no greater than 3 and the molar ratio available hydrogen peroxide/hypochlorites is at least one.
