碳纳米管在农药残留分析样品前处理过程中的应用

Application of carbon nanotube in pesticide residual sample pretreatment

碳纳米管(CNTs)作为一种新型纳米材料,其独特的分子结构、良好的化学稳定性、热稳定性和高比表面积,引起了国内外科学界的广泛关注。综述了CNTs在农药残留样品前处理,特别是在固相萃取(SPE)、固相微萃取(SPME)、分散固相萃取(DSPE)和分子印迹技术(MIT)等方面的研究成果,并对CNTs应用前景进行了展望,旨在为CNTs的深入研究和推广应用提供参考依据。

As a new kind of carbon materials,carbon nanotubes（CNTs）have attracted considerable interest because of their peculiar molecular structures and superior chemistry stability,thermal stability and high specific surface area,which could be considered as one of the ideal absorption materials. The recent applications progress of carbon nanotubes in the techniques of pesticide residual sample preparation was mainly focused, especially solid-phase extraction（SPE）, solid-phase microextraction（SPME） ,dispersive solid-phase extraction（DSPE）and molecularly imprinting technology（MIT）. In order to provide referential basis to carry out deep research and extending applications on CNTs, the application prospects of the CNTs were also briefly explored.
