Abstract
When a jet of electrolyte is impinging perpendicularly on a stationary circular electrode, there is a region of “uniform accessibility” similar to that on a rotating disk electrode. The objective of this study is to develop the impinging jet into a practical tool for electroanalytical applications. This geometry is attractive because there is no mechanical movement and the electrode can be easily adopted for the process streams and closed systems requiring pressure other than the ambient atmospheric pressure. A theoretical and experimental investigation has been made to determine the feasibility of a ring disk arrangement with an impinging jet. The reduction of ferricyanide ion and the cyclic voltammetry of a Cu2+/Cu reaction were used to determine the mass transfer characteristics and the collection efficiencies of platinum and nickel ring disk electrodes located within the uniform accessible regime of the impinged surface. It is found that the rotating ring‐disk theory could be used as a first approximation in the numerical computation.
