✦ Synopsis
From characteristic differential capacitance minima, for various concentrations and temperatures, adsorption potentials, 7, have been calculated. The change of adsorption potential with the mean ion activity, In a+, of the solution, and that of &/a In a* with temperature, are discussed. Resume-Des potentiels 7 d'adsorption sont calcults au moyen de minima de capacitance differentielle pour diverses concentrations et temperatures. La variation avec I'activite ionique moyenne In a& de la solution, ainsi que celle de %/a In a& avec la temperature sont discutees. Zusammenfassung-Aus den charakteristischen Minima der differentiellen Kapazitat wurden fur verschieden Konzentratione~ und Temperaturen die Adsorptionspotentiale berechnet. Die Aenderung des Adsorptionspotentials in Funktion der mittleren Ionenaktivit~t der Lbsung (log a& und die Variation von &/a log ai: mit der Temperatur werden diskutiert.
