ANALYTICAL METHOD FOR THE GRAVIMETRIC DETERMINATION OF URANIUM IN URANYL NITRATE SOLUTIONS (AFTER SEPARATION BY ETHER EXTRACTION)

Technical Report ·
OSTI ID:4226216
Uranium present in the aqueous sample, after suitable acidity adjustment, is extracted into diethyl ether using a continuous extraction procedure. Water is added to the extract, and the ether is removed by evaporation. The aqueous solution is diluted, and the uranium is precipitated with ammonium hydroxide. The precipitate is flltered off and dried. The dried precipitate is ignited at 900 deg C, and the uranium is weighed as U/sub 3/O/sub 8/. (auth)
