摘　　要：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。Microcapsules(MC) containing amide extracts were prepared and UO22+ in aqueous solution was extracted with the microcapsules. The formation of emulsion and the third-phase could be avoided because the water phase was separated from the extracts and solvent encapsulated in the MC. The counter-extraction and repeating uses of MC were also researched.
