CARBONATES OF OCTAVALENT URANIUM AND ALKALI METALS OR AMMONIUM

Patent ·
OSTI ID:4194978
A method is presented for producing water-soluble octavalent U compounds from uranium peroxide so that insoluble impurities can be removed. In an exannple 100 g of uranium peroxide filter cake was mixed with 70 g NaHCO/sub 3/ and 80 g of H/sub 2/O at 60 deg C for 30 min. Raising the temperature to 70 deg C for 30 min completely dissolved the solids. After filtration, 895 of the 945 cc of filtrate was heated to 40 to 45 deg C and 29 cc of 96% H/sub 2/SO/sub 4/ added along with 19 cc of 28% H/sub 2/O/sub 2/ and 30 cc of aqueous 30% NaOH. The uranium peroxide precipitate, when filtered and dried, weighed 65 g and contained 0.15% F. (T.R.H.)
