| 摘 要： | 通过分析几种中性磷类萃取剂(TBP、P205、P350、TRPO等)-稀释剂-水-酸体系中有机相的体积变化值、电导率值随着有机相中酸度变化的曲线和利用核磁共振与激光光散射等实验技术，探讨有机相中中性磷类萃取剂和H2O、酸的结合情况以及萃取过程中生成的微乳现象。观察到在HCl、H2SO4和HClO4体系的萃取过程中，在一定的酸度范围内，有机相中有聚集现象，即有反相胶束和微乳液生成。

| Abstract: | Focused on neutral phosphorus extractant (TBP,P205,P350,TRPO etc.)|diluent|water|acid system,this paper analyzes the changes of volume and conductivity following the acidity changes in organic phase,discusses the joint of water,acid and neutral phosphorus extractant in organic phase and phenomenon of microemulsion in extraction based on the experimental techniques such as NMR and Laser|Light|Scattering etc.It is demonstrated that aggregation (reversed micellar and microemulsion) is favored in the organic phase by a certain extend of acidity in the extraction of HCl,H-2SO-4 and HClO-4. |

| Keywords: | solvent extraction neutral phosphorus extractant aggregation microemulsion |
