摘要
随着对离子液体研究的不断深入,作为环境友好溶剂,离子液体以其蒸汽压小、热稳定性和化学稳定性良好等特性,在萃取技术方面取得了一定的进展。就离子液体在萃取金属离子、有机物、生物分子、稀土、脱硫脱氮以及与超临界CO2结合应用等,综述了国内外的研究进展,并探讨了离子液体在萃取时存在的问题及其发展前景。
With the deepening of the ionic liquid research, as environmentally friendly solvents, ionic liquid has made certain progress in extraction technology owing to several unique properties such as negligible vapor pressure, and good thermal and chemical stability characteristics. This paper summarizes the research progress abroad and at home from ionic liquids in extraction of metal ions, organic compounds, biological molecules, rare earth, desulphurization denitrification and application combined with supereritical CO2 and so on and discusses the problem of ionic liquids in extraction and its development prospect.
