A graphene material-based dispersive solid phase extraction method, comprising steps of performing pore-forming and activation on a graphene material, and obtaining an activated graphene material, the graphene material being graphene or modified graphene; and adding the activated graphene material to a chemical sample to be processed to obtain a mixture, and performing shaking and extraction on the mixture, the supernatant after centrifugal separation containing a target component to be detected. The method operates simply, and the separation effect is good. |
