Behavior of Microdisk and Microring Electrodes. Mass Transport to the Disk in the Unsteady State: Coupled Chemical Reactions

摘要

In this work, we discuss the solution of the differential equations in the cylindrical coordinate system for the case of a coupled CE reaction mechanism at a finite disk electrode. We use the properties of discontinuous integrals of Bessel functions to treat the mixed boundary conditions at the electrode surface and the surrounding insulator. The results are compared to previous analyses and we also make comparisons of various estimates of the chronoamperometric response for constant surface concentration conditions.
