Abstract

Ionic liquids (ILs) are widely used in separation methods such as chromatography and capillary electrophoresis due to their unique properties. This review discusses the prospects for using imidazole-based ILs as electrophoretic system modifiers in capillary zone electrophoresis and micellar and microemulsion electrokinetic chromatography for the determination of biologically active substances (amino acids, catecholamines, steroid hormones, and polyphenolic antioxidants). New approaches to selective electrophoretic determination and efficient online preconcentration of analytes with the participation of imidazolium ILs are considered; the application of developed approaches to the analysis of natural objects (urine, blood plasma, and plant extracts) is exemplified.

电泳分离和预浓缩过程中的离子液体

摘要

离子液体 (IL) 因其独特的性质而广泛用于色谱和毛细管电泳等分离方法。本综述讨论了在毛细管区电泳和胶束和微乳液电动色谱中使用咪唑基离子液体作为电泳系统改性剂来测定生物活性物质（氨基酸、儿茶酚胺、类固醇激素和多酚抗氧化剂）的前景。考虑了在咪唑鎓离子液体的参与下对分析物进行选择性电泳测定和高效在线预浓缩的新方法；举例说明了已开发方法在分析自然物体（尿液、血浆和植物提取物）方面的应用。
