| Résumé : | The kinetic study of various electrode reactions shows, in agreement with previous Russian work, that the action of the tetraalkylammonium ions can be explained, in absence of any complementary supporting electrolyte, in terms of a static ψ effect, generally complicated by blocking of the surface. In presence of an excess of supporting electrolyte however, another retarding process is observed, which, essentially depends on the nature of the supporting anion. It has been shown that this anionic effect does not follow the order of increasing adsorbability on mercury, but more likely results from direct interaction between these anions and the tetraalkylammonium cations (although co-operative adsorption may be an additional effect at electrode potentials on the negative side but not too far from the point of zero charge). The nature of this interaction is discussed, with special reference to the perchlorate ion, which exhibits the largest effect. © 1965. |
