Abstract

0.1 N KOH 전해질중에서 백금과 이산화납전극에 대한 요오드화이온의 전극반응을 삼각파 전위 주사법으로서 검토하였다. 그 결과는 다음과 같다.
백금전극에서는 0.45와 1.15 V vs. S. C. E.에서 I2와 IO-3가 생성되는 산화피이크가 형성되었다.
이산화납전극에서는 0.8, 1.3과 1.85 V vs. S. C. E.에서 세 개의 산화피이크가 나타나며, 이는 I2, IO-와 IO-3가 생성되는 전극반응에 기인하는 것이다.
The oxidation of iodide on platinum and lead dioxide electrodes in 0.1 N KOH electrolytes were investigated using the cyclic voltammetric technique. Results are summarized as following:
At platinum electrode the formations of I2 and IO3- occurred on 0.45 and 1.15 V vs. S.C.E., respectively.
At lead dioxide electrode three anodic peaks of I2, IO- and IO3- was formed on 0.8, 1.3 and 1.85 V vs. S.C.E., respectively.
