用制备的包覆酰胺类萃取剂的微胶囊研究了其在水溶液中对ＵＯ２２＋的萃取条件。并对反萃取及微胶囊的重复使用作了初步探讨．结果表明，微胶囊包覆萃取剂后，隔开了有机相和水相，可避免乳化及三相的产生。 The extraction conditions of UO22 + in aqueous solution were studied with prepared microcapsules coated with amide extractant. And the repeated use of the back extraction and microcapsules was discussed. The results show that the microcapsules coated with extractant, separated from the organic phase and the aqueous phase, to avoid the formation of emulsification and three-phase.
