石墨烯类材料在水处理和地下水修复中的应用

摘要

作为一种性质优异的吸附材料,石墨烯类材料对有机物和重金属等多种水污染物均有出色的吸附能力,因此其在水处理和地下水修复工作中的应用前景在近几年备受关注.当前的研究总体上尚停留在实验室模拟阶段,在提高材料饱和吸附量的同时,研制出低成本、稳定性强、易于再生利用且环境友好的石墨烯类材料是今后的发展趋势.本文对石墨烯类材料的种类及制备方法进行了归纳总结,对他们在水处理和地下水修复中的应用研究情况进行了综述,对当前研究中存在的问题进行了分析,最后对未来的研究和应用前景进行了总结和展望.%As an excellent adsorbent material, graphene-based materials have superior adsorption capacity on various water pollutants including heavy metals and organic pollutants, which has received considerable attention due to its enormous potential in application of water treatment and groundwater remediation in recent years. The current research is generally still in the stage of laboratory simulation. The development of graphene-based materials with low cost, strong stability, easy recycling and environment friendly as well as high saturation adsorption capacity is the future developing trend. This review summarizes the classification and fabrication methods of graphene-based materials. Besides, the applications in water treatment and groundwater remediation are reviewed. Furthermore, the main problems at present and the application prospects for future research are proposed.
