Description

The extraction behavior of americium from acid solutions by a mixture of 3-phenyl-4-benzoyl-5-isoxazolone and tri-n-octyl phosphine oxide in carbon tetrachloride medium has been investigated in 1--6 M nitric acid. It is shown that Am(III) can be removed along with U(VI) and Pu(IV) quantitatively from 1 M nitric acid in a single contact and that Am(III) can be selectively stripped by using higher (> 6 M) nitric acid concentrations. The distribution profile for Am(III) has been evaluated in the presence of varying amounts of U(VI) and Nd(III) in varying nitric acid media. The distribution behavior of several fission products has also been reported
