| titleOfInvention | PROCEDURE FOR THE REEXTRACTION OF ACTINIDES AND MAINLY URANIUM. |
| abstract | Actinides, especially uranium, neptunium and plutonium, which have been extracted from nitric acid solutions into an organic solvent (preferably tributylhosphate or trilaurylamine in an inert diluent such as a hydrocarbon) are stripped from this solvent by nitrous acid. The nitrous acid is prepared in situ from sodium nitrite and nitric acid or by passing nitric oxide into dilute aqueous nitric acid maintained out of contact with air. In the examples the process is carried out in a bank of mixersettlers which is totally enclosed, the acid and organic solutions being introduced at opposite ends to give countercurrent conditions. Nitric oxide is continuously bubbled into the acid to maintain the nitrous acid concentration. |
