离子液体由于其独特的性质和对许多不同物质的良好溶解性，已被应用于化学工业的各个领域。离子液体缺乏挥发性和可燃性是使其在各种应用中具有优势的共同特征，例如电池中的电解质，合成中的溶剂和催化剂，润滑剂，制造功能材料的溶剂，萃取，气体吸收剂，本文综述了离子液体在液-液微萃取中的典型应用利用离子液体的独特性质，包括离子液体与小型化样品分离方法的结合，即单滴微萃取（SDME）、分散液-液微萃取（DLLME）和基于中空纤维的液相微萃取（HF-LPME），以提高其灵敏度和选择性。离子液体微萃取技术具有成本低、操作简单、快速、准确等优点，是化学分析中的有力工具。
Because of their unique properties and good solubility for many different materials, ionic liquids (ILs) have been applied in all areas of the chemical industry. ILs' lack of volatility and flammability are the common characteristics that give them an advantage in various applications such as electrolytes in batteries, solvents and catalysts in synthesis, lubricants, solvents to manufacture functional materials, extraction, gas absorption agents, etc. The major purpose of this review paper is to provide an overview of the representative applications of ILs in liquid–liquid microextraction (LLME) techniques that benefit from the unique properties of ILs, including the developments achieved by combination of ILs with miniaturized approaches to sample preparation—namely, single drop microextraction (SDME), dispersive liquid–liquid microextraction (DLLME) and hollow fiber-based liquid phase microextraction (HF-LPME)—to improve both their sensitivity and selectivity. IL-based microextraction provides unique advantages, including low cost, simplicity of operation, speed, precision and accuracy, making ILs a powerful tool in chemical analysis.
