离子液体是一种环境友好的绿色溶剂.因其具有独特的理化性能,如蒸汽压低、不易挥发、稳定、黏度以及在水中的溶解性可调等特点,在样品前处理技术中可以替代传统的有机溶剂作为萃取溶剂,提高了分析的选择性和灵敏度.本文对基于离子液体的液相微萃取技术(单滴液相微萃取、中空纤维液相微萃取、分散液液微萃取)在环境污染物分析中的应用进行综述.
Ionic liquid is an environmentally friendly green solvent because of its unique physical and chemical properties, such as low vapor pressure, non-volatile, stable, viscosity and solubility in water and other characteristics of adjustable, in the sample pretreatment technology can replace the traditional Organic solvent as the extraction solvent to improve the selectivity and sensitivity of the analysis.In this paper, liquid-based liquid phase microextraction (single-drop liquid-phase microextraction, hollow fiber liquid-phase microextraction and dispersive liquid-liquid microextraction) The application of material analysis is reviewed.
