Abstract
A method for the construction of carbon paste electrodes (CPE) is desc ribed. Here ferrocene is used as the insoluble electroactive species, graphite powder as conductor and sulfuric acid as binder. The CPE thus prepared prevents ferrocenium ions from diffusing towards the bulk so lutions. Voltammetric, chronopotentiometric and chronoamperometric exp eriments performed with these CPEs show that the different preparation methods yield different electrochemical parameters for the ferrocene- ferrocenium system.
