TUBULAR BAND MICROELECTRODE .1. DESIGN AND ELECTROCHEMICAL-BEHAVIOR

The effect of supporting electrolyte concentration and sample how rate on the electrochemical behavior of a tubular band microelectrode was studied and compared to the results obtained by simulation. The condit ions for the current to be independent of the hydrodynamic flow rate a re established. The experimental results are compared to those obtaine d by digital simulation based on the explicit hopscotch method. These calculated results are also compared to those obtained for microband a nd infinite planar geometries. It was concluded that this microelectro de very rapidly reaches a stationary state, providing a stable and fas t response to concentration changes in the solution, as is required fo r analytical purposes.
