摘要
水污染威胁人类发展。高效、低耗能的水处理技术开发已成为研究热点。吸附比其他技术有低耗能,易再生和成本低等优点。其关键是找到合适的材料。石墨烯较于其他材料有高比表面积,负电性强等特性,是优异的吸附材料。本论文总结了近年来石墨烯在吸附去除重金属离子和有机染料的工作,展望了石墨烯及复合材料对以上污染物吸附的应用前景。
Water pollution threatens human development. The development of water treatment technology with high effciency and low energy consumption has become a research hotspot. Compared with other technologies, adsorption has the advantages of low energy consumption, easy regeneration and low cost. The key is to fnd the right materials. Compared with other materials, graphene has the characteristics of high specifc surface area and strong electronegativity and is an excellent adsorption material. This paper summarizes the recent work of graphene in adsorption and removal of heavy metal ions and organic dyes, and looks forward to the application prospect of graphene and its composites in adsorption of the above pollutants.
