The Behavior of Disk Electrodes: Optical Imaging of the Concentration Distribution over a Disk Electrode under Galvanostatic Conditions

Abstract

This paper describes the theoretical and experimental determination of the integrated time dependent concentration distribution of an electrogenerated species over a disk electrode embedded in an insulated plane. We have derived this result for case of constant applied flux (chronopotentiometry). The experimental technique used for observing the integrated concentration distribution over the electrode was imaging by a low noise charge coupled device camera with time and spatial resolution of approximately 20 ms and 20 micrometers respectively. The experiment demonstrates the contribution of the tertiary current distribution across the surface of the electrode. Keywords: Charge coupled devices; Electrogeneration; Real time.
