摘　　要：氧化石墨烯作为一种新型纳米材料在水处理领域受到了人们的广泛关注,由于其具有较大的比表面积,丰富的含氧官能团,良好的亲水性,独特的物理结构,使其可吸附水中的重金属离子,且吸附能力超过诸多目前常用的吸附剂。但同时由于氧化石墨烯结构和性质的原因,限制了其在水处理领域中的发展,为了解决这个问题,可通过氧化石墨烯与其他物质结合形成氧化石墨烯复合物。介绍了氧化石墨烯的结构和性质,以及其对水中重金属离子的吸附机制及受控的影响因素;同时,也综述了氧化石墨烯复合物对水中重金属离子的吸附机制,以及其解吸与重复利用能力;此外,对氧化石墨烯及其复合物作为吸附剂去除水中重金属离子的应用潜力进行了总结和展望。Graphene oxide has attracted widespread attention in water treatment field as a new nanomaterial.Because of its large specific surface area,abundant oxygen-containing functional groups,excellent hydrophilia,and unique physical structure,it can adsorb heavy metal ions from water and its adsorption capacity is better than many kinds of common adsorbents.However,its structure and property have limited its development in water treatment field.This problem can be solved by combining graphene oxide and other materials to form graphene oxide composites.This review introduces the structure and property of graphene oxide,its adsorption mechanism for heavy metal ions in water and the influence factors.At the same time,this review summarizes the adsorption mechanism of graphene oxide composites for heavy metal ions in water and its desorption and regeneration abilities.In addition,it summarizes and predicts the application potential of graphene oxide and its composites as adsorbents to remove heavy metal ions from water.
