Solid- phase extraction technique based on multi- walled carbon nanotubes and its application in food safety detection

多壁碳纳米管(MWCNTs)是一种新型的纳米碳材料,具有性质稳定、吸附能力强、易修饰和成本低廉等特点,近年来被作为一种新型吸附材料广泛应用于固相萃取技术中。本文简要介绍了碳纳米管的制备方法,重点介绍基于MWCNTs的固相萃取模式及其在食品安全检测样品前处理中的应用,并就存在的问题及今后发展方向进行了讨论。

As a novel nano- carbon materials,multi- walled carbon nanotubes（ MWCNTs） exhibits the advantages of excellent physical and chemical stability,strong adsorption,easy functionalization and low cost.As a kind of good adsorption material,it has been widely used in solid phase extraction technology recently. In this paper,the preparation method of MWCNTs was described,and the application of solid phase extraction based on MWCNTs in sample preparation of food safety detection was mainly reviewed.The limit of MWCNTs as well as the prospect was discussed.
