摘　　要：利用量热滴定法研究皂化P507萃取有机相中反向胶束的形成和滴水过程中微乳状液的形成.求得临界胶束浓度、胶束形成常数K、聚集数n以及热力学函数,并用激光动态光散射仪测定胶团和微乳颗粒的流体力学半径。In the organic phase of saponated P507(2-ethylhexylphosphonic acid mono-2-ethyl-hexyl ester) the formation of reversed micelle and microemulsion in the process of titration with water has been studied by calorimetry method.The critical micelle concentration (CMC),aggregation number (n),formation constant(K) and thermodynamic function of micellization were determined.The hydro-dynamic radius of each droplet was also obtained by the laser light scattering experiment.

关 键 词：溶剂萃取 反向胶束 微乳液
