There are electrochemical processes in which little or no supporting electrolyte is used. This is the case, for instance, of the study of overlimiting currents [34, 41,42], and of microelectrode [43-45], and different voltammetric techniques [17, 18, 46-48], in which the absence of supporting electrolyte increases the sensitivity of the detection of the redox species. In this section, a general procedure for solving the electrodiffusion equations is presented. The procedure is based on determining...
