Electrochemical oxidation of hypochlorite at platinum anodes

Oxidation of hypochlorite has been studied by cyclic voltammetry with a rotating-ring-disc assembly. Experiments were carried out with sodium chloride or sodium sulphate solutions with hypochlorite present or absent. Hypochlorite is oxidized at the platinum disc anode and the species formed by this oxidation are detected with the platinum ring cathode. From the shape of the current—potential curves at the ring electrode and from the relation between the ring and the disc currents it has been concluded that the first step of the hypochlorite oxidation is the formation of the chloroxyl radical (ClO)
