Local redox potential measurement

Abstract

A local potential measurement method that can be easily used in an anaerobic solution was settled and the potential probe was tested with a simple and fast electrochemical system. From the local potential value, plotted versus the distance to the working electrode, the concentration profile of the electrochemically consumed species can be calculated. The comparison of this experimental concentration profile to the theoretical one, which is based on Nernst hypothesis, enables us to assess the screening effect induced by the potential probe on the potential and current distributions. Thus, it is possible to calculate the potential profile that would be recorded by an ideal probe.
