Process for the treatment of anolyte brine

摘要

A process for removing dissolved halogen gas and oxyhalide ions from an aqueous alkali metal halide solution containing them which comprises reacting said aqueous alkali metal halide solution with an inorganic peroxide, and adjusting the pH of said aqueous alkali metal halide solution to a pH within the range from about 6 to about 11 with an inorganic base, whereby a purified alkali metal halide solution of reduced concentration of said dissolved halogen gas and oxyhalide ions is produced.
