Ionic liquids (ILs) are novel nonmolecular solvents. Their unique properties, such as high thermal stability, tunable viscosity, negligible vapor pressure, nonflammability, and good solubility for inorganic and organic compounds, make them excellent candidates as extraction media for a range of microextraction techniques. Many physical properties of ILs can be varied, and the structural design can be tuned to impart the desired functionality and enhance the analyte extraction selectivity, efficiency, and sensitivity. This paper provides an overview of the applications of ILs in liquid phase microextraction technology, such as single-drop microextraction, hollow fiber based liquid phase microextraction, and dispersive liquid-liquid microextraction. The sensitivity, linear calibration range, and detection limits for a range of target analytes in the methods were analyzed to determine the advantages of ILs in liquid phase microextraction.
离子液体（ILs）是新型的非分子溶剂。它们具有独特的性质，如高热稳定性、可调粘度、可忽略的蒸气压、不燃性以及对无机和有机化合物的良好溶解性，使其成为一系列微萃取技术的优秀萃取介质候选物。许多 ILs 的物理性质可以改变，并且可以对结构设计进行调整以赋予所需的功能并提高分析物萃取的选择性、效率和灵敏度。本文概述了 ILs 在液相微萃取技术中的应用，例如单滴微萃取、基于中空纤维的液相微萃取和分散液液微萃取。分析了这些方法中各种目标分析物的灵敏度、线性校准范围和检测限，以确定 ILs 在液相微萃取中的优势。
