Process for degrading hypochlorite
It is an object of the present invention to provide an improved means and method for the degradation of hypochlorite in alkali waste solutions. It is a further object of the present invention to provide a more effective and less costly method for the degradation of hypochlorite. The foregoing objects and others are accomplished in accordance with the present invention, generally speaking, by providing a process to degrade hypochlorite into chloride and oxygen which includes contacting an aqueous hypochlorite basic solution with a catalyst comprising about 1--10 w/w % cobalt oxide and about 1--15 w/w % molybdenum oxide on a suitable substrate. In another embodiment a similar process for degrading lithium hypochlorite is provided in which waste solution concentration is lowered in order to minimize carbonate precipitation. 6 tabs.
