DESTRUCTION OF SODIUM HYPOCHLORITE IN SOLUTIONS FROM A CHLORATE ELECTROLYTIC CELL

摘要

ABSTRACT OF THE DISCLOSURESodium hypochlorite present in a chlorate solutionfrom a chlorate electrolytic cell is destroyed by adding tothe solution a solution compound selected from ammonia andammonium salts such as ammonium chlorite and ammonium sul-phate. The destroying agent is added to the solution up-stream of the chlorate crystallizer in such an amount asto provide a molar ratio of hypochlorite to ammonia of lessthan 1.5. During reaction the pH is maintained at 6.0 to6.5.
