二氧化硫的电化学氧化过程Ⅲ．SO_2在聚钴卟啉膜电极上的氧化机理

Anodic Oxidation of Sulfur Dioxide Ⅲ.The Mechanism of Oxidation of Sulfur Dioxide on the Poly CoPP Electrode

采用循环伏安法、稳态法、计时电位法等研究了ＳＯ＿２在聚钴卟啉膜电极上的电化学氧化过程，并和ＳＯ＿２在贵金属电极上的行为进行了比较。

The electrochemical oxidation process of sulfur dioxide on the poly CoPP electrodewas studied by cyclic voltammetry, steadystate method,chronoamperometry and chronopo-tentiometry.The actions of sulfur dioxide have been compared with that on the nobel metalelectrods. The mechanism of the oxidation of sulfur dioxide has been discussed.
