摘要
作为复杂样品分析过程中至关重要的步骤,样品前处理技术的进步对分析化学的发展具有重要意义。磁性固相萃取(magnetic solid phase extraction,MSPE)是一种以磁性或可磁化材料作为吸附剂的新型样品前处理技术,因具有操作简便、萃取时间短、抗杂质干扰能力强和良好的生物相容性等优点,在食品样品前处理领域具有广阔的应用前景。近年来,随着各种吸附材料制备技术的快速发展,基于新型磁性纳米材料的磁性固相萃取技术在食品安全检测中的应用越来越广泛。本文综述了近5年来基于石墨烯/氧化石墨烯(graphene/graphene oxide,G/GO)、碳纳米管(carbon nanotube,CNT)、金属有机框架材料(metal-organic frameworks,MOFs)、共价有机框架材料(covalent organic frameworks,COFs)、分子印迹聚合物(molecularly imprinted polymers,MIPs)、纳米复合材料以及功能化聚合物材料的磁性固相萃取技术在食品安全检测中应用的最新进展,并对其在食品安全分析检测领域的发展前景进行了展望。
Technology trends in sample pretreatment,a crucial step in the analysis of complex samples,are of great significance to the development of analytical chemistry.Magnetic solid phase extraction(MSPE)is a novel sample pretreatment technique using magnetic or magnetizable materials as adsorbents.Thanks to its advantages including easy operation,short extraction time,strong anti-interference ability and good biocompatibility,MSPE represents one of the most promising approaches in the field of sample pretreatment.In recent years,with the rapid development of various adsorbent preparation techniques,novel magnetic nanomaterials-based MSPE is widely used for the isolation and enrichment of a variety of compounds in foods.In this review,we summarize the up-to-date advances in the application of MSPE based on graphene/graphene oxide(G/GO),carbon nanotube(CNT),metal organic framework materials(MOFs),covalent organic framework materials(COFs),molecularly imprinted polymers(MIPs),nanocomposite materials or functional polymer materials in food safety detection,and we discuss future development prospects in this field.
