Graphene based materials including graphene,graphene oxide,reduced graphene oxide and graphene quantum dots are a new kind of multifunctional carbon nanosubstances with sigle layer structures.And their unique physicochemical properties such as specific surface area,remarkable thermal and chemical stability,strong electrostatic stacking property,hydrophobic interaction and hydrogen bond make them have a broad prospect in separation science.Research progress of graphene based materials in capillary electrophoresis(CE) in recent years are reviewed,such as additives of background electrolyte,stationary phases of capillary electrochromatography column,modification material of electrode for CE-electrochemical detection and adsorbents in sample pretreatment for CE.The future development and potential application of graphene based materials in CE are also discussed in this review.
