Abstract
Galvanostatic double pulse 방법으로 백금전극을 사용해서 염소산이온의 전극반응기구를 조사하였다. double current pulse(음극펄스를 먼저 주고 다음에 양극펄스를 주었을 때)를 주었을 때 전류밀도 20∼25ma/cm2 범위에서 염소산이온의 전극반응기구가 다음과 같이 가정되었다. 더 높은 전류밀도 40∼90ma/cm2 범위에서, 염소산이온의 전극반응기구는 다음과 같이 가정되었다.

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-.
