Investigation on Carbon Fiber Microelectrodes (Ⅴ)--The Kinetics of Ferrocene and Its Derivatives on Carbon Fiber Ultramicroelectrodes

Abstract

Abstract: The present paper reports the voltammetric behaviour of ferrocene and its five derivatives in various organic solvents, as well as the effects of scan rate of potential and supporting electrolyte on the currents investigated with both caron fiber ultramicroelectrode of radius 5 μm and glassy carbon electrode for comparison. The diffusion coefficients, electron transfer rate constants and half-wave potentials of the six compounds in different solvents were determined. The experimental results for the ferrocene in acetonitrile are in good agreement with those from literatures, but the most other data presented in this paper have not been reported yet in literatures.

Key words: Carbon fiber microelectrode, Electron transfer rate constant, Diffusion coefficient, Ferrocene and its derivatives
