摘要
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
In the research of ordinary extraction chemistry,more attention has been paid on the composition and structure of extracted adduct.Through the investigation of several typical extraction system commonly used in hydrometallurgy,the influence of the formation of reversed micelles on distribution ratio must be considerd in the system with amine extractant and in the synergic system of acid and neutral extractants.In this paper,studies on reversed micelles and microemulsions in extraction system were reviewed.Studies on interfacial chemistry model of uranium extracted by P204 and the reversed micelles model of uranium sulfate by the trioctylamine have been systematically investigated.The occurring of third phases in some extraction system was explained in term of the formation of Winsor Ⅲ microemulsion.
