摘　　要：石墨烯为sp2杂化的单层碳原子构成的六角形蜂巢晶格结构,表面卷曲多褶皱,富含π电子,热稳定性及化学稳定性良好,这些优良特性符合样品前处理中吸附剂的要点,故石墨烯在样品前处理领域有广泛的应用前景。本文拟对以石墨烯及其复合材料作为固相微萃取介质在样品前处理方面的应用进行简要评述。Graphene,asinglelayerof carbonatoms with sp2 hybridizationarrangedin a hexagonal honeycomblattice,has multiple folded and curlysurface,richπelectronics,good thermal and chemical stability.As a result,graphene has been intensively used in the field of sample preparation.In this paper,the application of graphene and its composites as adsorbents in solid-phase microextraction is reviewed.
