THE DETERMINATION OF CHROMIUM IN URANOUS FLUORIDE

Technical Report ·
OSTI ID:4194905
Chromium can be determined ia UF/sub 4/ by treating the sample with ammonia and hydrogen peroxide and removing fluorides by volattlization as ammonia fluoride under controlled heating. The solution is evaporated to dryness, taken up in nitric acid, evaporated to dryness, and the residue taken up in water. The chromium is determined with diphenal carbazide after oxidation with ammonium persulfate and silver nitrate. (C.J.G.)
