摘要：

The synergistic effect of tri-n-octylmethylammonium chloride (capriquat, QCl) on the solvent extraction of Np(V) by thenoyltrifluoroacetone (TTA, HT) was investigated over the pH range 2-8. The reaction for the extraction of Np(V) was shown to be: NpO2+ + T- + 2(QT)o = (NpO2T2QT)o. The logarithm of the extraction constant, log Kex, was 2.3. It was ascertained that the interaction between QCl and TTA during extraction, (QCl)o + (HT)o = (QT)o + H+ + Cl-, seriously affected the extraction of Np(V) and that the effective extraction of Np(V) could be obtained in the presence of excess HT over QCl. © 1979.
