High efficiency hypochlorite generation

The oxidation of chloride ion at DSA anodes gives higher yields of hypochlorite than were obtained at Pt or graphite electrodes.It is also shown that the problem of hypochlorite reduction at the cathode in undivided cells can largely be overcome by use of a ‘reduced area’ cathode. These two improvements have both been included in a new cylindrical hypochlorite cell capable of a 70% conversion of a 0.048 mol. dm−3 NaCl solution to NaOCl with a production rate of 50 gh−1 ‘active chlorine’.
