Application of ionic liquids in the preparation of extraction chromatographic materials for metal ion separations: Progress and prospects

摘要: ABSTRACTOver the last two decades, extraction chromatography, a form of liquid chromatography employing as stationary phase any variety extractants in an appropriate organic solvent sorbed on solid support, has emerged important tool for number analytical- and preparative-scale metal ion separations. Recent studies which ionic liquids (ILs) have been evaluated replacements molecular solvents normally used liquid–liquid suggest that improvement performance chromatographic materials might be effected by use IL basis phase. In this report, approaches to preparation new sorbents incorporating ILs are described resultant various separations is reviewed. addition, promising areas future work identified.
