Abstract

Pesticides are one of the main exogenous harmful residues in traditional Chinese medicines( TCMs),and the potential safety problems caused by pesticides affect the sustained and healthy development of TCMs. Carbon nanotubes( CNTs) possessed unique structure and properties,and widely used in analytical chemistry and other areas. In this review,the structure of CNTs and preparation method of composite material were summed up. Then,the application of CNTs in the pre-treatment technique of pesticides residues such as solid-phase extraction,solid phase micro-extraction,dispersive solid-phase extraction,matrix solid phase dispersion for detection of pesticides in different matrices were discussed in detail. In addition,the characteristics of pesticides in TCMs and maximum levels of pesticide residues in TCMs were investigated. Finally,the development and problems of CNTs in the determination of pesticide residues in TCMs were prospected.

摘要

农药是中药材中主要的外源性有害残留之一，农药引发的潜在安全问题影响着中药的可持续健康发展。碳纳米管（CNTs）具有独特的结构和性能，广泛应用于分析化学等领域。本文综述了碳纳米管的结构及复合材料的制备方法。然后，详细讨论了碳纳米管在固相萃取、固相微萃取、分散固相萃取、基质固相分散等农药残留预处理技术中用于检测不同基质中农药的应用。此外，还研究了中药材中农药的特性及中药材中农药残留的最大限量。最后，对碳纳米管在中药材农药残留测定中的发展及存在的问题进行了展望。
