โฆ Synopsis
Cadmium deposition from solutions of varying ionic strength and coumarin concentration has been studied polarographically.
Under certain conditions two polarographic waves are obtained, both corresponding to cadmium deposition. This effect has been explained by the variation with potential of the orientation of adsorbed coumarin molecules.

Zusammeufassnng-Die
Abscheidung von Kadmium aus LSsungen verschiedener Ionenstarken und Kumarinkonzentrationen wurde polarographisch untersucht.
Unter gewissen Bedingungen erhllt man zwei Reduktionswellen, die beide mit der Kadmiumabscheidtmg verkntipft sind. Dieser Effekt wurde durch eine Orientierungs%nderung der Adsorbierten Kumarinmolektile mit dem Potential erklart.
