摘　　要：凹凸棒石(ATP)在诸多方面都表现出优良性能,所以普遍被用在复合材料制作方面。而氧化石墨烯(GO)作为石墨烯的一种衍生物,其表面存在许多含氧官能团,反应活性和亲水性十分优异,而修饰改性后的GO在有机溶剂中具有更好的相容性与分散性,其复合材料表现出的优异性能受到研究学者的关注。综述了氧化石墨烯/凹凸棒石复合材料制备方法,插层化学法、溶液共混法、磁力-超声法等,系统总结了该复合材料在污水处理中对金属离子和有机染料,尤其是亚甲基蓝的吸附情况,讨论了该复合材料对水中污染物降解的效果,并对氧化石墨烯/凹凸棒石复合材料的未来发展进行展望。Attapulgite(ATP)has excellent properties in many aspects,so it is widely used in the fabrication of composite materials.As a derivative of graphene,graphene oxide(GO)has many oxygen-containing functional groups on its surface,which has excellent reactivity and hydrophilicity.The modified GO has better compatibility and dispersion in organic solvents,and the excellent performance of its composites has attracted the attention of researchers.In this paper,the preparation methods of graphene oxide/palygorskite composites are reviewed,mainly including intercalation chemical method,solution blending method,magnetic ultrasonic method,etc.The adsorption of metal ions and organic dyes,especially methylene blue,on the composite in sewage treatment is systematically summarized,and the degradation effect of the composite on pollutants in water is briefly discussed.The future development of graphene oxide/attapulgite composites is prospected.
