SYNERGISTIC EXTRACTION OF U(VI) FROM NITRIC ACI D SOLUTION WITH N-DECANOYWORPHOLINE AND TBP IN BENZENE

Chen Wei-yan

Abstract

The synergistic extraction properties and mechanism of uranium(Ⅵ)from nitric acid solution with N-decanoyworpholine(DMPHL) and TBP at (25±1)℃ are investigated. The influences of extractant concentration, nitric acid concentration, temperature and salting out agent on the distribution ratio are studied. The extraction equilibrium constants are calculated.
