Abstract
Electrolysis of impure saline solutions containing dissolved iron and manganese causes deposits to form on the anodes of such electrolysis cell which rapidly reduces the efficiency of the cell. Pretreating the impure saline solutions with sodium hypochlorite solution formed from the reaction products of the electrolysis cell precipitates the iron and manganese dissolved therein and effectively prevents the formation of the deleterious deposits on the anode of said electrolytic cell.
