    Determination of Stability Constants for Np(Ⅳ) and Pu(Ⅳ) With N,N-dimethyl-3-oxa-glutaramic Acid

      Graphical Abstract
      • Abstract
    • The action of synthesizing of N,N-dimethyl-3-oxa-glutaramic acid (DOGA) with Np(Ⅳ) and Pu(Ⅳ) is studied by means of the extraction. The results of study show that DOGA with Np(Ⅳ), Pu(Ⅳ) can form complexes whose rations of coordinating are 3∶1 at 25 ℃. The stability constants of the complexes are: Pu(DOGA)~+_3, lg β_1=6.52,lg β_2=9.14,lg β_3=15.77;Np(DOGA)~+_3,lg β_1=6.95,lg β_2=10.435,lg β_3=14.93.
