Voltammetry at a Microdisk Electrode

Application ID: 12877

Voltammetry is modeled at a microelectrode of 10um radius. In this common analytical electrochemistry technique, the potential at a working electrode is swept up and down and the current is recorded. The current-voltage waveform ("voltammogram") gives information about the reactivity and mass transport properties of the analyte.

Microelectrodes are popular in electroanalysis because they provide high current densities with a small quantity of active electrode material. The short diffusion timescales to a microelectrode mean that the steady-state result is accurate and so a Stationary study can be used. The Secondary Current Distribution and Transport of Diluted Species interfaces are used to couple charge and mass transfer with an electrode reaction.
