摘要
氧化石墨烯(GO)复合膜基于良好的亲水性、丰富的官能团、较大的比表面积及化学稳定性等优异性能在膜分离领域备受关注。该文综述了GO复合膜的制备方法,包括真空过滤法、旋涂法、层层自组装法、掺杂法和共混法等,介绍了其在微污染水体和工业废水深度处理领域的研究进展,探讨了GO复合膜对污染物的分离机理,并对其在水处理领域的应用前景和今后的研究方向进行了展望。
Graphene oxide(GO)composite membranes have attracted much attention in the field of membrane separation due to their excellent hydrophilicity,abundant functional groups,large specific surface area and chemical stability.In this paper,the preparation methods of GO composite membranes were reviewed,including vacuum filtration,spin coating,layer-by-layer self-assembly,doping method and blending.Meanwhile,the research progress of GO composite membranes in the field of water treatment(micro-polluted water treatment and advanced treatment of industrial wastewater)was introduced.In addition,the separation mechanism of pollutants by GO composite membranes was discussed.Finally,the application prospects and future research directions of GO composite membranes in the field of water treatment were prospected.
