Simulation of the microdisc problem in spherical co-ordinates. Application to electrochemiluminescence homogeneous analysis

Abstract

The chemical transformations of electrogenerated ion-radicals of a number of complex organic compounds may be accompanied by emission of photons. An electrogenerated chemiluminescence (ECL) quantum contains information both on the kinetics of the heterogeneous electrode processes and on the subsequent homogeneous chemical reactions in the solution. Application of ECL to solution analysis provides advantages in comparison to electrochemical methods. We demonstrate a new approach for numerical simulation of the microdisc problem in spherical co-ordinates and apply it to ECL homogeneous analysis under non-steady state electrolysis.
