长碳链的脂肪胺从硝酸溶液中萃取铀、钍、钚和其他金属离子的研究工作很多,但在萃取机理方面目前尚不很清楚.前两文中已经较系统地探讨了三一正十二胺萃取铀和钍的机理.为了进一步研究在硝酸体系中胺类萃取机理,看来还需要对胺类萃取硝酸的机理进行深入的探讨.卡斯韦尔((Carswell)和劳伦斯(Lawrance)曾经在研究三辛胺萃取钍的工作中指出,三异辛胺(TIOA)的苯溶液对硝酸的萃取是随着水相硝酸浓度的增加而增加.接着谢夫钦柯(?)等和曼绍夫(?)等研究了三正辛胺(TNOA)及二辛胺萃取硝酸的机
There are many studies on the extraction of uranium, thorium, plutonium and other metal ions from nitric acid solution by aliphatic amines with long carbon chains. However, the mechanism of extraction is not yet clear. The first two articles have discussed systematically three positive twelve Amine extraction uranium and thorium mechanism.In order to further study the mechanism of amine extraction in nitric acid system, it seems that the mechanism of amine extraction of nitric acid also need to be discussed in depth.Caswell ((Carswell) and Lawrence (Lawrance) In the study of the trioctylamine extraction of thorium, it was pointed out that the extraction of nitric acid from the benzene solution of tri-isooctylamine (TIOA) increased with the increase of nitric acid concentration in the aqueous phase, followed by Chevchenko (?) Et al. ?) And other studied the three n-octylamine (TNOA) and dioctylamine nitric acid extraction machine
