摘　　要：膜萃取是膜过程和液液萃取过程相结合的一种新型分离技术 .与通常的液液萃取过程不同 ,膜萃取传质中没有相的分散过程 ,具有其特殊的优势 .Membrane extraction process is a new separation technology which combines the membrane process with liquid-liquid extraction. Unlike conventional solvent extraction, membrane extraction is a dispersion-free extraction process. It offers several advantages over conventional solvent extraction. While the advanced progress on mass transfer characteristics and process intensification of membrane extraction in hollow fiber modules are introduced in detail.
