Diffusion-controlled chronoamperometry at a disk electrode.
An accurate formula exists for describing the decay of the current following the imposition of extreme concentration polarization on a disk electrode under diffusion-controlled conditions. It has been amply validated by diverse simulations and is presented here in a more compact form than hitherto. The formula finds application beyond the realm of potential-step chronoamperometry.
متن کاملElectrochemical behaviour of iodide at a rotating platinum disk electrode in methanol
The oxidation of iodide at a rotaling platinum disk electrode in methanol has been studied. At low concentrations only one oxidation wave is seen, but at higher concentrations two steps are discerned. This is in accordance with the theory, assuming that the equilibrium between iodide, ttiiodide and iodine is reached fast and the oxidation of iodide to iodine occurs reversibly. only in approxima...
متن کاملNumerical analysis of a model for nickel-iron alloy electrodeposition on rotating disk electrode
To better understand the nickel-iron electrodeposition process, we have developed one-dimensional numerical model. This model addresses dissociation, diffusion, electromigration, convection and deposition of multiple ion species. The reaction mechanism in this model differs in that Ni2+ and Fe2+ are the electroactive species and NiOH+ and FeOH+ are not involved whatsover. To take account of the...
متن کاملHow does the double layer at a disk electrode charge?
Because of the nonuniform accessibility of its surface to ion transport from the solution, the double layer at an inlaid disk electrode charges anomalously in response to a potential step. A numerical simulation of the problem shows that the overall current versus time transient differs little from that for a single resistor in series with a single capacitor. Nevertheless, the charging process,...
