Research Developments for Applications of Graphene in Sample Preparation

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