摘　　要：石墨烯基复合材料具有较大的比表面积、较高的表面能,对污染物具有较强的吸附能力,可用于去除水中的污染物,从而达到净化污水的目的。本文综述了几种石墨烯基复合材料的制备和其对水中化学类物质,如重金属离子、有机染料和其他污染物的吸附特性,并简述了溶液的酸度、接触时间和金属离子初始浓度等对石墨烯基复合材料吸附污染物的影响。Graphene based composite materials have larger specific surface area,high surface energy,strong adsorption ability to the pollution; they can remove the pollutants from the water,so as to achieve the purpose of purifying water. The preparation methods and adsorption properties to chemical substances in water,such as heavy metal ions,organic dye and other pollutants,of several kinds of graphene based composite materials were introduced,and the influence of the p H,contact time,initial concentration of metal ions on the adsorption of graphene composites were discussed.
