Abstract
An electrolytic cell and process for the simultaneous production of hydrogen peroxide and hypochlorous ion. The electrolytic cell has an anode chamber housing an insoluble anode capable of oxidizing halide ion, a cathode chamber housing a gas diffusion cathode capable of oxidizing an oxygen-containing gas to produce hydrogen peroxide, a membrane separating the anode and cathode chambers, and means for supplying water containing halide ion to the anode chamber and an oxygen-containing gas and an electrolyte to the cathode chamber, whereby hypohalide and hydrogen peroxide are produced in the anode chamber and the cathode chamber, respectively. Also disclosed is a process for treating water using the electrolytic cell.
