✦ Synopsis

A detailed study of the vibrated dropping mercury electrode has been made_ Electrocapillaryphoresis is shown to be primarily responsible for the increased diffusion current due to the application of a transverse alternating field_ A few typical results of the investigation of the effects of the magnitude and frequency of a transverse alternating field on the polarographic limiting current in a solution of 0•001 M Cd2+ and 0-001 M HgH respectively in 0-1 M KCl and on the polarographic maximum in a solution of 0-001 M HgH in 0-1 M KCI are presented.

Resiime-Etude detailee de l'electrode a gouttes de mercure vibrante. L'electrophoft!se capillaire est reconnue responsable d'un courant de diffusion accru par imposition d'un champ alternatif transversal. Quelques resultats typiques denotent les effets de l'intensite et de la frequence d'un tel champ sur Ie courant polarographique limite d'une solution 0,001 M Cd H ou Hg2+, par ailleurs 0,1 M KCl, ainsi que sur Ie maximum polarographique correspondant au second cas.

Zusammenfassung-Die vibrierte Quecksilber-Tropfelektrode war Gegenstand einer ausftihrlichen U ntersuchung.
