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。
By analyzing the volume change of the organic phase in several neutral phosphorous extractants (TBP, P205, P350, TRPO, etc.), the conductivity value changes with the curve of the acidity in the organic phase, Laser light scattering and other experimental techniques to explore the organic phase neutral phosphorus extractant and H2O, the combination of acid and the extraction process of the micro-emulsion generated phenomenon. During the extraction of HCl, H2SO4 and HClO4 systems, it was observed that there was aggregation in the organic phase within a certain range of acidity, ie, the formation of reverse micelles and microemulsions.
