由于其高度可调的性质和突出的物理化学性质,离子液体(IL)已被广泛报道用于合成多种磁性纳米颗粒(MNPs)。基于IL的磁性纳米颗粒(IL-MNPs)在磁分散固相萃取(MDSPE)中具有巨大的潜力。目前,IL-MNPs已成功应用于药物中MDSPE样品的预处理,杀虫剂,兽药,重金属,染料,添加剂,和农产品中的蛋白质,食品和饮料,环境水,和生物样本。在这次审查中,综述了IL-MNPs的制备及其在MDSPE中的应用。描述了用于制备IL-MNPs的引入IL的结构特征和用于获得IL-MNPs的合成途径。包括物理涂层和化学键合方法。然后根据不同的改性材料对IL-MNPs进行分类和描述,包括硅基材料,碳基材料,金属有机框架,分子印迹聚合物和其他有趣的大/小分子。最后,进一步明确了IL-MNPs在MDSPE背景下的研究前景和发展方向。
Due to their highly tunable nature and outstanding physicochemical properties, ionic liquids (ILs) have been widely reported for use in the synthesis of multitudinous magnetic nanoparticles (MNPs). IL-based magnetic nanoparticles (IL-MNPs) have great potential in magnetic dispersive solid-phase extraction (MDSPE). At present, IL-MNPs have been successfully applied in the pretreatment of MDSPE samples from medicines, pesticides, veterinary drugs, heavy metals, dyes, additives, and proteins in agricultural products, foods and beverages, environmental water, and biological samples. In this
review, the preparation of IL-MNPs and their application in MDSPE are comprehensively summarized. The structural characteristics of the introduced ILs used to prepare the IL-MNPs and the synthetic routes employed to obtain the IL-MNPs are described, including physical coating and chemical bonding methods. The IL-MNPs are then classified and described according to different modified materials, including silica-based materials, carbon-based materials, metal-organic frameworks, molecularly imprinted polymers and other interesting large/small molecules. Finally, the research prospects and development directions of IL-MNPs in the context of MDSPE are further identified.
