THE ABSORPTIOMETRIC DETERMINATION OF IRON IN URANIUM TETRAFLUORIDE

OSTI ID:4236547

Uranium tetrafluoride is dissolved by boiling with a solution of aluminum chloride in nitric and hydrochloric acids. The tetrafluoride dissolves due to the formation of complex (AlF/sub 6/)/sup 3-/ ions, and nitric acid oxidizes the uranium to the hexzvalent state. The solution is cooled, and thioglycolic acid/ammonium citrate and ammonia/ ammonium carbonate solutions are added. Citrate ions prevent the precipitation of uranium ions in alkaline solution, while carbonate suppresses the ansorbancy due to uranium complexes. The iron concentration is measured absorptiometrically as the thioglycolate complex. (auth)
