多壁碳纳米管(MWCNTs)作为一种新型的纳米碳材料,与传统的吸附材料相比,碳纳米管具有较大的比表面积、良好的机械稳定性、稳定的化学性质及较强的吸附能力等优点,且前处理操作简便、萃取时间短、有机溶剂使用量少,近年来被作为一种新型吸附材料广泛应用于农药残留检测方法中。通过介绍多壁碳纳米管的结构与性能,以及多壁碳纳米管在农药残留检测样品前处理中的应用,对多壁碳纳米管在农药残留检测中存在的问题及未来发展方向进行了展望。
Multiwalled carbon nanotubes (MWCNTs) as a new type of nano-carbon materials, compared with the traditional adsorption materials, carbon nanotubes have a larger specific surface area, good mechanical stability, stable chemical properties and strong adsorption Ability and other advantages, and the pretreatment is simple, extraction time is short, the use of organic solvents less, in recent years as a new type of adsorbent widely used in pesticide residue detection methods. By introducing the structure and properties of multi-walled carbon nanotubes and the application of multi-walled carbon nanotubes in the pretreatment of pesticide residues, the problems and future development of multi-walled carbon nanotubes in the detection of pesticide residues are prospected .
