摘要

石墨烯是由单层碳原子经sp2杂化形成的二维蜂窝状晶格结构,其比表面积高达2630m2/g,具有非常高的吸附容量,在水处理方面具有广阔的应用前景。详细介绍了石墨烯及其复合材料在吸附重金属离子、有机污染物中的研究进展,分析了其吸附机理,并指出了石墨烯及其复合材料的后续研究方向,同时对其在吸附领域的应用前景做了展望。

Abstract

Graphene has a two-dimensional honeycomb lattice structure,which is formed by monolayer of carbon atom via sp2 hybridization.With a specific surface area of 2630m2/g,graphene has an extremely high adsorption capacity,leading to a broad application prospect in water treatment.The research progress on adsorption of organic pollutant and heavy metal in wastewater by graphene and its composite were introduced,and analyzied its adsorption mechanism.Finally,the future research direction of graphene and its composites,as well as its application prospect in the field of adsorption were pointed out.
