Diffusion-limited adsorption at spherical electrodes

Abstract

Both the diffusion coefficient and maximum surface concentration of a surfactant may be calculated from potentiostatic current.time curves obtained using spherical electrodes. The theoretically-derived relation between the maximum surface concentration, diffusion coefficient, and time at which maximum surface coverage is attained was tested by adding tetrabutylammonium ion to a solution of Cd(II) in 0.1 M perchloric acid.
