✦ Synopsis

Separation of Americium from Neptunium or Plutonium by Back-Extraction. Experiments show that the Am(III) was quantitatively stripped from the organic phase with 0.05-0.2 M HN03, while most of the Np(IV) and Pu(IV) is remained in the organic phase (Table I). From Table I it can be seen that the separation factor of Am and Np or Am and Pu is more than 50. Consequently, this method may be applied to separating Am from Pu(IV) and Np(IV).
