A constant current coulometer for the high precision analysis of uranium

  • 1. European Commission, Joint Research Centre, Institute for Reference Materials and Measurements, Geel (Belgium)

Description

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 extremely high accuracy. The device was applied to the coulometric titration of uranium. The chemical part of the system was adapted and improved and a reliable procedure was developed. The method is highly accurate, standard deviations lie around 0.06% relative. It is an absolute method and directly traceable to the SI units. (orig.). With 6 figs., 3 tabs
