多壁碳纳米管在农药残留检测中的应用进展

Progress in Applications of Multi-walled Carbon Nanotubes in Pesticide Residue Detection

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。

As a novel nano-carbon materials, multi-walled carbon nanotubes(MWCNTs) exhibits the advantages of high surface area,excellent chemical,mechanical,thermal stability and strong adsorption capacity,while the sample preparation has the advantages of simplicity,short extraction time and low consumption of organic solvents. As a kind of good adsorption material,it has been widely used in pesticide residue detection technology recently. In this paper,the structure and properties of MWCNTs is described, and the application of pesticide residue detection based on MWCNTs in sample preparation is mainly reviewed. Finally, the potential resolutions to the existing problems and the future development of MWCNTs in pesticide residue detection are prospected.
