摘　　要：室温离子液体是由正负离子组成的室温为液体的熔融盐,因其具有极低的蒸汽压、可设计性和特殊的选择溶解能力等独特的性质,使得其在萃取分离有机物及金属离子、液相微萃取和汽油柴油中脱硫及碱性氮化物等领域都有着广泛应用。综述了离子液体在萃取分离上的应用进展。Ionic substances with melting points close to room temperature were referred as room - temperature ionic liquids, which showed lots of unique properties, e.g. environmentally benign, nonvolatile, designable and were good solvents for a wide range of beth organic and inorganic materials. Ionic liquids are widely used in extraction and separation processes, e.g. extraction and separation of metal ions and organic compounds, headspace liquid - phase micro extraction, removal of basic nitrogen compound from distilled diesel and desulphurization of gasoline. In this paper, the recent application of ionic liquids in extraction and separation were reviewed.
