▎ 摘　　要

As a novel nanomaterial, graphene has been widely applied in many fields such as material, catalysis, adsorption and separation science due to its unique characterisics such as large surface area, good thermal and chemical stability, strong hydrophobicity, easy chemical modification, etc. The applications of graphene in sample pretreatment such as solid. phase extraction, dispersive solid phase extraction, solid phase microextraction, stir rod sorptive extraction, matrix solid phase dispersion and so on are reviewed in the paper.
