摘要
合成并研究了10种双取代酰胺萃取铀、钍、裂片元素的情况,结果表明,取代己内酰胺的萃取性能优于非环状双取代酰胺。和1mol/1的TBP相比,取代己内酰胺萃取铀的能力比TBP强,萃取钍的能力和TBP接近。除OCLA外,酰胺对于铀钍的分离性能均比TBP好,酰胺对Zr-Nb的去污性能优于TBP。还初步探讨了酰胺类萃取剂结构与性能的关系。
The solubility of five kinds of sulfoxides in diluents (such as kerosene and aromatic hydrocarbon diluents)and their extracting ability for thorium and uranium from nitric acid solution are presented. The results show that two dialkyl sulfoxide with branch chain, such as di (2-ethylhexyl) sulfoxide (DEHSO)and di(1-methylheptyl)sulfoxide(DMHpSO) ,are not only completely miscible with kerosene, but also superior to tri-n-butyl-phosphate(TBP)in some abilities. The relations between the structure of the sulfoxides and their extracting ability are briefly discussed.
