摘要
电膜萃取(EME)作为一种新型的、方便高效的样品前处理技术,可以应用于食品检测、药物分析、环境监测、生物分析等领域的复杂检材前处理中。通过优化溶液酸度、萃取电压、萃取时间、支撑液膜的组成等,实现短时间内从各种基质样品中萃取目标物。介绍了EME的传质原理和模式,分析了中空纤维、平板膜、芯片、凝胶EME模式的特点。列举了电膜萃取食品中有害物质的应用研究,以及复杂基质中组织胺、麻醉药品和精神药品、医源性药物、多肽和金属离子快速提取中的实际应用,未来可在膜材料及联用技术方面进行深入研究(引用文献38篇)。
Electromembrane extraction(EME),as a novel,user-friendly and highly efficient sample preteartment method,can be applied to the sample pretreatment of complex samples in fields of food detection,drug analysis,environmental monitoring,and biological analysis.By optimizing the acidity of the solution,extraction voltage,extraction time,and composition of the supporting liquid film,the targets can be extracted from various matrix samples in a short period of time.The mass transfer principle and modes of EME were introduced,and the characteristics of EME modes,including hollow fiber,parallel membrane,chip,and gel,were analyzed.The application research of EME of harmful substances in food and the practical application in the rapid extraction of histamine,narcotic drugs and psychotropic substances,iatrogenic drugs,polypeptides and metal ions from complex matrices were listed.Membrane materials and combined technology could be further studied in the future(38 ref.cited).
