| 摘要: 研究了N,N,N',N'-四丁基丙二酰胺(TBMA)以甲苯为稀释剂,从硝酸介质中萃取硝酸和铀(Ⅵ)的机理。在该萃取体系中,TBMA和HNO3形成TBMA·HNO3,和U(Ⅵ)形成为UO2(NO3)2·3TNMA.借助红外光谱分析,确定了在萃合物中NO3-不参与UO22+的直接配位,并对萃合物中配体的配位方式进行 |

| Abstract: The extraction mechanism of HNO3 and UO22+ with TBMAin toluene from the nitric acid medium has been studied.At the experimental condition, HNO3 and TBMA can form HNO3 TBMA, and the composition of extracted species is UO2(NO3)2·3TBMA.It was testified that the in the xtraction species UO2(NO3) 2·3TBMA, NO3- did not directly participate in coordination of uranyl (Ⅵ) ion by IR, and the coordination mode of the complex was also discussed. |
| Keywords: N, N, N', N' - tetrabutylmalonamide (TBMA) extraction uranium (Ⅵ) coordination model |
