| Abstract: | 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 |
