Process to minimize the's non contamination of alkali metal chlorate in hidroxidos) obtained by eletrolise of alkali metal halide solution in a cell eletrolitica,And the process for decomposition of alkali metal halide brine in cedulas eletroliticas

摘要

A method of minimizing chlorate formation when brines are decomposed in diaphragm type electrolytic cells which comprises adding brine containing dissolved nickel values periodically to said cell while continuing operation of the cell. The nickel values can be added whenever the chlorate content of the alkali metal hydroxide increases to again minimize chlorate formation.
