  • Published:1993-11-15

本文研究了聚苯并咪唑为修饰膜并交换上Fe(CN)~6^3-的修饰电极的稳定性、适宜酸度条件和电化学行为, 测定了膜中电荷转移扩散系数并用该修饰电极研究了对抗坏血酸的催化氧化作用。

关键词: 维生素C, 化学修饰电极, 催化氧化, 聚苯并咪唑

Using polybenzimidazole (PBI) as coated film and Fe(CN)63- attached through ion-exchange to the polymeric coatings, the authors have prepared a new modified electrode. It shows that the electrode is quite stable and has large effective charge diffusion coefficient In addition, it has been proved to have catalytic effect on the oxidation of ascorbic acid in aqueous solution

Key words: VITAMIN C, CHEMICAL MODIFIED ELECTRODE, CATALYTIC OXIDATION, POLYBENZIMIDAZOLE
