The mechanisms of the electrode reaction of chlorate ion were investigated, using Pt-electrode, by means of the technique of galvanostatic double pulses. For double current pulses (a cathodic pulse followed by an anodic pulse), the mechanism of the electrode reaction of chlorate ion over a current density range from 20 ma/cm2 to 25 ma/cm2 was suggested as the following: ClO3- Ⅰ→n1c ClO2- Ⅱ→n2c ClO- Ⅰ'→n1a ClO2- Ⅱ'→n2a ClO4- For a higher current density from 40 ma/cm2, it was suggested as the following: ClO3- Ⅲ→nc ClO- Ⅰ'→n1a ClO2- Ⅱ'→n2a ClO4- or ClO3- Ⅲ→nc ClO- Ⅲ'→na ClO4-.
