✦ Synopsis

Prior concentration-cell

experiments with carbon electrodes are reviewed, and the ion responsiveness of several carbon electrodes is evaluated in terms of a newly defined selectivity coefficient. The ion selectivity of the carbon electrode and previously observed potential drifts are interrelated. New experimental studies of potential drifts are reported, and the results are satisfactorily interpreted by means of equivalent circuits.

R&auu&Revue

des experiences antbieures sur des piles de concentration a electrodes de carbone; un coefficient de selectivite nouvellement d&ini permet devaluer la sensibilite ionique pour plusieurs electrodes de carbone. On met en relation avec les variations de potentiel pr&demment observees la selectivite ionique de l'electrode de carbone.

De nouvelles determinations exp&-imentales sont d&rites et leurs resultats sont inter@tes d'une man&e satisfaisante au moyen de circuits equivalents.
