Determination of Diffusion Coefficients of Anions at a Rotating Silver Disc Electrode.

Abstract

A silver rotating disc electrode has been employed to obtain diffusion coefficients for a number of anions which form insoluble films at the electrode surface (sulfide, selenide, thiocyanate, selenocyanate, iodide and bromide) and one which does not (cyanide). It is found that the Levich equation is obeyed even though a film is continuously forming on the silver surface. Except for cyanide, the electrode reactions appear irreversible, based on the shape of the anodic voltammograms and the cathodic stripping peaks. (Author)
