| Abstract: | Asimple analytical expression for the chronoamperometric current at finite disk electrodes, which is accurate at any time, is given by:it=4nFDRT0θ/(1+θ ) f(Υ)=0.7852+0.8862τ-1/2+0.2148τ1/2/(1.128+τ1/2) Where n is the number of electrons involved in the oxidation of substance R, Fthe faraday. DRis the diffusion coefficient of R, τ0 the radius of the disk electrode, CR*is the bulk concentration of substance R, t is the time and τ=4DRt/r02r0, 0=expnF(E-E0)/RT]. |
