【摘要】 石墨烯由于具有独特的构型、较大的比表面积和较强的化学活性,使其具有较好的吸附能力,受到环境工作者的广泛关注。但未经处理的石墨烯由于存在较强的π-π相互作用、且粒径小,易团聚,限制了其在环境领域中的应用,为了解决这个问题,常对石墨烯进行改性。文章综述了石墨烯的一些改性方法,同时也综述了改性石墨烯对水中有机污染物和重金属离子的吸附机制,以及对气体吸附方面的研究进展。更多还原

【Abstract】 The graphene has received wide attentions in environment field as a new nanomaterial. It had good performance of adsorption ability because of a unique pore structure, the larger specific surface area and strong chemical activity. But, graphene development in environment field is limited cause of the structure. Graphene modification can be used to solve the problem. This review introduces the preparation method of graphene modification, and its application in removal of organic pollutants and heavy metal ions, and gas adsorption.更多还原
