Abstract

A method is given for dissolving and reprecipitating an oxalate carrier precipitate in a carrier precipitation process for separating and recovering plutonium from an aqueous solution. Uranous oxalate, together with plutonium being carried thereby, is dissolved in an aqueous alkaline solution. Suitable alkaline reagents are the carbonates and oxulates of the alkali metals and ammonium. An oxidizing agent selected from hydroxylamine and hydrogen peroxide is then added to the alkaline solution, thereby oxidizing uranium to the hexavalent state. The resulting solution is then acidified and a source of uranous ions provided in the acidified solution, thereby forming a second plutoniumcarrying uranous oxalate precipitate.

CONCENTRATION OF Pu USING AN IODATE PRECIPITATE

Patent Fries, B.A.

A method is given for separating plutonium from lanthanum in a lanthanum fluoride carrier precipitation process for the recovery of plutonium values from an aqueous solution. The carrier precipitation process includes the steps of forming a lanthanum fluoride precipi- . tate, thereby carrying plutonium out of solution, metathesizing the fluoride precipitate to a hydroxide precipitate, and then dissolving the hydroxide precipitate in nitric acid. In accordance with the invention, the nitric acid solution, which contains plutonium and lanthanum, is made 0.05 to 0.15 molar in potassium iodate. thereby precipitating plutonium as plutonous iodate and the plutonous iodate is separated frommore »« less
CALCIUM OXALATE CARRIER PRECIPITATION OF Pu

Technical Report Maraman, W.J. ; Beaumont, A.J. ; Christensen, E.L. ; ...

A plant-scale procedure for concentrating Fu and Am in slag and crucible (metal reduction residues) and other recovery solutions by a calcium oxalate carrier precipitation is described. Conclusions from exploratory laboratory tests on the variables affecting the efficiency are included. (auth)
METHOD OF SEPARATING Pu FROM METATHESIZED BiPO$sub 4$ CARRIER

Patent Knox, W.J. ; Thompson, S.G.

A process is given for separating uranium, neptunium, and/or plutonium from a bismuth hydroxide carrier by selective dissolution of these actinides with nitric acid of a concentration of from 0.05 to 0.5N.
BISMUTH PHOSPHATE CARRIER PROCESS FOR Pu RECOVERY

Patent Finzel, T.G.

An improvement in the bismuth phosphate carrier precipitation process for recovering plutonium is described. It has been found that a more granular and more easily filterable carrier precipitiite is formed if the addition of the bismuth and phosphate ions is effected by first adding 9/10 of the bismuth ions necessary, then slowly adding all of the source of the phosphate ions to be incorporated in the precipitate, while digesting at 75 C and afterwards incorporating the remainder of the total bismuth ions necessary
Method for producing high carrier concentration p-Type transparent conducting oxides

Patent Li, Xiaonan ; Yan, Yanfa ; Coutts, Timothy J. ; ...

A method for producing transparent p-type conducting oxide films without co-doping plasma enhancement or high temperature comprising: a) introducing a dialkyl metal at ambient temperature and a saturated pressure in a carrier gas into a low pressure deposition chamber, and b) introducing NO alone or with an oxidizer into the chamber under an environment sufficient to produce a metal-rich condition to enable NO decomposition and atomic nitrogen incorporation into the formed transparent metal conducting oxide.
