Limiting Local Current Densities for Electrodes Located on the Walls of a Rectangular Channel with Laminar Flow; Asymptotic Solution and Experimental Verification

Abstract

Equations were derived for calculating the local and average limiting current densities for an electrode located on the wall of a rectangular channel. The validity of the equation for the average limiting current density was checked experimentally by the deposition of Hg2+. The equation expressing the local limiting current density as a function of the length and width of the electrode was verified by the deposition of Ag from an electrolyte labeled with ^110mAg.
