Abstract
A constant current coulometry device was designed, built and evaluated . It is capable of controling the coulometric titration process and to deliver the necessary current and time supplies/measurements with ext remely high accuracy. The device was applied to the coulometric titrat ion of uranium. The chemical part of the system was adapted and improv ed and a reliable procedure was developed. The method is highly accura te, standard deviations lie around 0.06% relative. It is an absolute m ethod and directly traceable to the SI units.
