摘　　要：氧化石墨烯凭借其优异物化性质和独特结构而被广泛应用,但氧化石墨烯具有生物毒性和环境危害性,存在于水环境中的氧化石墨烯具有极强的迁移性能,因此,研究其在多孔介质中的运移是一个热点。论文从迁移模型和实验条件两方面介绍了国内外学者的研究进展,模型方面,目前已经提出CFT模型、双点位迁移模型和离子追踪模型;实验方面,主要考虑了悬浮液离子强度、p H值、温度、有机物等对氧化石墨烯在多孔介质中运移的影响。最后,基于现有的研究成果,提出相关研究展望。Graphene oxide nanoparticles（GONS） has being widely used owing to its excellent physicochemical properties and unique structure, and it has strong migration in water environment, but it has biological toxicity or environmental hazards,so the study of its migration is a hot spot. In this paper, the model and experimental studies were summarized. In model studies, the CFT model, the two-site kinetic attachment model and particle tracking model have been proposed. In experiment, migration factors such as the ionic strength, p H value, temperature, organic in suspension were considered. Finally, based on study results some corresponding research prospects were proposed.
