The Behavior of Disk Electrodes. Optical Imaging of the Concentration Distribution Over a Disk Electrode under Galvanostatic Conditions Species Selective Gas Chromatographic Detectors
Abstract
In this paper, we describe 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 the 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 20ms and 20micro m respectively. The experiment demonstrates the contribution of the tertiary current distribution across the surface of the electrode.
