METHODS OF ELECTROLYSIS, OXYGEN-SELECTIVE ANODES USED IN SUCH METHODS AND THEIR PREPARATION

摘要

Novel oxygen selective electrode comprising a coating on said anode consisting of delta manganese dioxide. This outer coating on the anode may be placed on the anode electrochemically by electrolyzing an acid saline solution having dissolved therein sufficient manganous chloride. Sufficient manganese dioxide is plated on said anode when the chlorine evolution essentially ceases during electrolysis.
