摘要
高效的样品前处理是实现准确分析的前提条件。分散固相萃取(dispersive solid-phase extraction,DSPE)是一种通过将固体吸附剂分散在液体分析物中,从复杂基质中分离和净化不同的分析物的方法。这种方法具有高效、快速、选择性强、易操作等优点,已经被广泛应用于环境、食品、药物、生物等领域的样品前处理中。本文首先对DSPE做了概述,然后以DSPE的设计原理为切入点,阐述固体吸附剂的不同分散方式、固体吸附剂的种类和性质对样品前处理过程的影响。随着纳米科技的蓬勃发展,尤其是磁性纳米材料、分子印迹聚合物、碳质材料及金属有机框架化合物等新材料的发现为DSPE注入了新的活力。本文重点讨论了这几种新材料在动物源性食品兽药残留方面的应用情况,并对DSPE的未来发展方向进行了预测,以期为相关技术人员提供新的思路。
Efficient sample pretreatment is a prerequisite for accurate analysis.Dispersive solid-phase extraction(DSPE)is a method for separating and purifying various analytes from a complex matrix by dispersing a solid sorbent in a liquid analyte.This method has the advantages of high efficiency,speed,selectivity,and simplicity of operation,and has been widely used in sample pretreatment in environmental,food,pharmaceutical,and biological fields.This paper firstly provided an overview of DSPE and then took the design principle of DSPE as an entry point to explain the various dispersing methods of solid adsorbents and the impact of the types and properties of solid adsorbents on the sample pretreatment process.With the booming development of nanotechnology,the discovery of new materials such as magnetic nanomaterials,molecularly imprinted polymers,carbonaceous materials and metal-organic frameworks in particular has brought new vitality to DSPE.This paper focused on the application of these new materials to veterinary drug residues in animal foods and predicted the future direction of DSPE to provide new ideas for related technicians.
