THE COLORIMETRIC DETERMINATION OF CHROMIUM IN URANIUM COMPOUNDS

Technical Report ·
OSTI ID:4103988
A method for the rapid microdetermination of chromium in uranium compounds was developed. The chromium is oxidized to the hexavalent state with permanganate and the excess permanganate is reduced with bromide. The chromium concentration is then determined by developing and measuring the color of the chromium diphenylrarbazide complex. This combination of oxidant and reduciant gives this method advantages over similar methods published; i.e., excess reductant can be used without close control and a stable chromium diphenylcarbazide is formed. Quantities of from one to ten micrograms of chromium can be determined with a 10% limit of error at the 95% confidence level. (auth)
