用旋转环盘电极技术研究含中位四（ 对磺基苯基） 卟啉合铁（ＦｅＴＰＰＳ） 的聚吡咯膜覆盖的玻碳电极上的氧还原过程． 结果表明该修饰膜的存在降低了氧还原的过电位，还原产物中有Ｈ２Ｏ２ ，过程用异相氧化还原催化（ＥＣ） 机理解释． 与金或铂比较，碳是较好的电极基体材料，适合于产生破坏水中有机物所需的过氧化物． 在酸性介质中氧在该膜修饰电极上的还原速度比在中性介质中大，由ＫｏｕｔｅｃｋｙＬｅｖｉｃｈ 关系式求出修饰膜中催化剂和分子氧反应的表观速度常数值．
The ring-and-ring electrode technique was used to study the oxygen reduction process at the glassy carbon electrode covered with polypyrrole film containing Fe (superscript +) 4 (p - sulfophenyl) porphyrinato iron The results show that the presence of the modified film reduces the overpotential of oxygen reduction, H2O2 reduction products, the process of using heterogeneous redox catalytic (EC) mechanism to explain. Compared with gold or platinum, carbon is a preferred electrode matrix material that is suitable for generating the peroxides needed to destroy organic matter in water. In acidic media, the reduction rate of oxygen on the modified electrode is larger than that in neutral media. The apparent velocity constant of the catalyst and molecular oxygen in the modified film is obtained from the Koutecky-Levich equation.
