经典的萃取化学侧重于萃合物的组成和结构的测定。我们认为在研究铀液液萃取机理时必须考虑萃取剂在萃取有机相中的聚集现象,只有从形成反相胶束和微乳液的观点,才能更本质揭示萃取机理。研究了P204 萃取铀的界面化学模型和三正辛胺萃取硫酸铀酰的反相胶束模型,并解释了萃取体系第三相与Winsor Ⅲ微乳液的关系
Classic extraction chemistry focuses on the determination of the composition and structure of the extracts. We think that in the study of uranium liquid-liquid extraction mechanism, it is necessary to consider the aggregation of extractant in the extracted organic phase. Only from the point of view of the formation of reverse micelles and microemulsions, the extraction mechanism can be more revealed. The interfacial chemical model of uranium extraction from P204 and the reverse micelle model of uranyl sulfate extraction from tri-n-octylamine were studied, and the relationship between the third phase of extraction system and Winsor Ⅲ microemulsion was explained
