Une nouvelle technique de l'electrolyse: l'electrode a convection thermique application aux methodes electrochimiques d'analyse

In this new electrolysis technique, the mechanical stirring generally used in electrochemical methods of analysis is replaced by thermal stirring obtained by creating a temperature gradient between a stationary electrode and an initially immobile solution. The heating of the electrode by the Joule Effect is the simplest means of realising this. Experience has shown that this method of stirring gives excellent reproducibility of results and confers great stability on the electrolysis current of the imposed potential. The applications of this technique that spring to mind are mainly, the following of intensity-potential curves of various oxidation-reduction systems and the graphical representation of coulometry at constant potential by the simple plot of log i = f(t).
