| 摘 要： | The dependence of THMA extraction behaviour for U(VI) and Th(IV) on nitric acid concentration,THMA concentratioin and molecular structure of extracted complex has been studied.For nitric acid solutions of 3.0 mol/L a coordinative mechanism may possibly dominate in the extraction of metal catioins,The complex composition of UO2(NO3)2(THMA)2,Th(NO3)4(THMA)2 and Th(NO3)4(THMA03 are proved.

| Abstract: | The dependence of THMA extraction behaviour for U(VI) alld Th(IV) on nitric acid concentration, THMA concentration and molecular structure of extracted complex has been studied. For nitric acid solutions of 3.0mol/L a coordinative mechanism may possibly dominate in the extraction of metal cations. The complex composition of UO2(NO3)2(THMA)2,Th(NO3)4 (THMA)2 and Th(NO3)4 (THMA)3 are proved. |
