Rotating Ring-Disk Electrodes

Abstract
A digital simulation technique has been employed to treat the steady‐state and transient ring current behavior at the rotating ring‐disk electrode (RRDE) for cases where the intermediate generated at the disk electrode undergoes a first‐ or second‐order homogeneous chemical reaction leading to a nonelectroactive species. Where comparisons were possible, the results were found to be in good agreement with previous approximate theoretical treatments. Working curves are provided which allow determination of rate constants of the homogeneous reactions from ring‐current‐rotation rate data.
