Zusammenfassung

Es wurde festgestellt, daß bei dieser Bestimmung eine photochemische Reaktion gleichzeitig mit der elektrochemischen Reduktion des vierwertigen Plutoniums abläuft. Experimentelle Beweise werden angeführt. Die Störung kann vermieden werden, wenn die coulometrische Titration im Dunkeln durchgeführt wird.

Summary

Data are provided in support of a photochemical reaction which takes place simultaneously with the electrochemical reduction of quadrivalent plutonium during the controlled potential coulometric determination of plutonium in a mixture with uranium. The interfering effect of this reaction is overcome by placing the cell in a dark environment.
