Abstract

833,981. Separation of uranium-233 and protoactinium. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Nov. 12, 1947 [Aug. 18, 1947], No. 30124/47. Class 39(4). Uranium-233 is separated from neutronirradiated thorium by forming an aqueous nitrate solution of the thorium of pH not less than 2 and contacting the solution with methyl iso-butyl ketone which extracts the uranyl nitrate. The thorium may be dissolved in concentrated nitric acid and the pH adjusted with ammonia, calcium hydroxide, or caustic alkali. Before extraction the solution may be saturated with calcium, ammonium, or zinc nitrate. Protoactinium is either extracted or not, according to the pH of the solution ; it may be recovered from the aqueous phase by making the solution about 1- normal in nitric acid and extracting again with methyl iso-butyl ketone.
