▎ 摘　　要

NOVELTY - Graphene material-based dispersive solid phase extraction method involves performing pore-forming and activation of graphene or modified graphene as a graphene material, producing an activated graphene material, adding the activated graphene material to to-be-processed chemical sample, shaking, extracting, and detecting supernatant containing target component after centrifugal separation. USE - Graphene material-based dispersive solid phase extraction method (claimed). ADVANTAGE - The graphene material-based dispersive solid phase is extracted by simple method with excellent separation effect.
