Diffusion-Controlled Current at the Stationary Finite Disk Electrode. Theory.

Abstract

Rigorous expressions for diffusion-controlled currents at a stationary finite disk electrode are derived through use of the Winer-Hofp technique. The chronoamperometric curve obtained varies smoothly from a curve represented by the Cottrell equation to a steady state value similar to that obtained for a spherical electrode as time elapses. The solution can be expressed also as the Cottrell term multiplied by a power series in the parameter sq. rt (Dt/a), where a is the electrode radius. The present work is discussed in terms of the coefficient of the first term in this formulation. (Author)
