IMPROVEMENTS IN OR RELATING TO RECOVERY OF RADIOACTIVE CAESIUM

Patent ·
OSTI ID:4155816

A method is given for converting cesium phosphotungstate precipitated from fission product solutions to more useful compounds. In an example. an 8 N HNO/sub 3/ solution of fission products was treated with 12-tungstophosphoric acid to precipitate Cs. The precipitate was collected. washed. dissolved in NaOH, and re-precipitated. The precipitate was then dissolved in NH/sub 4/OH and passed through an ion-exchange column containing De-acidite FF in hydroxide form. The Cs hydroxide resulting was neutralized with H/sub 2/SO/sub 4/ and dried. (T.R.H.)
