摘要
磁性离子液体是一种磁性功能化的离子液体材料,不仅具有蒸气压低、液程宽、热稳定性好等特点,还具备可设计性强、产物易于分离、可回收重复利用等优势,能够解决微萃取技术中相分离困难和重复利用率低等难题,在食品分析预处理领域具有非常广泛的应用前景。本文梳理总结了用于食品分析预处理的磁性离子液体的种类及制备方法,系统介绍了磁性离子液体分离富集食品中生物胺类、药物类、食品添加剂类、持久性有毒类、无机重金属类化学污染物的应用研究进展,并对基于磁性离子液体在食品分析预处理技术的未来发展前景进行了展望。
Magnetic ionic liquids(MILs),as a type of magnetic functionalized ionic liquid materials,are characterized by low vapor pressure,wide liquid range,and excellent thermal stability and possess strong designability,easy product separation,and recyclability for repeated use.These properties enable them to tackle problems with microextraction techniques such as difficult phase separation and low reusability.MILs have a broad application prospect in the field of sample pretreatment for food analysis.This article systematically summarizes the varieties and preparation methods of MILs for sample pretreatment for food analysis,reviews recent progress in the application of MILs in the separation and enrichment of various chemical contaminants in foods,including bioamines,drugs,food additives,persistent toxic substances,and inorganic heavy metals.It concludes with an outlook on the future development of MIL-based sample pretreatment techniques for food analysis.
