Abstract:
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.
