Abstract

The Warburg impedance of a rotating disk electrode is analyzed by means of an inverse Laplace transformation of the governing differential equation. This new formulation reduces the problem to a partial differential equation for which approximate solutions are known. The results obtained agree with exact numerical values for a wide range of low and high frequencies.
