吸附技术除去环境中的不同种类的污染物通常简单有效。石墨烯具有很大的理论比表面积及氧化石墨具有的官能团表明其具有潜在的吸附能力。在过去的几年中,许多研究重点在于石墨烯或者其复合物在空气和水污染处理上面的应用。综述了最近石墨烯基纳米材料用于吸附水溶液中离子的研究进展。氧化石墨的改性或者是石墨烯和金属氧化物、有机物的结合所生成的不同纳米材料,其吸附能力和分离效率都得到较大提高。
Adsorption techniques are often simple and effective in removing different types of contaminants in the environment. Graphene has a large theoretical surface area and the functional groups of graphite oxide indicate its potential adsorption capacity. In the past few years, many researches have focused on the application of graphene or its composites in air and water pollution treatment. The recent progress of graphene based nanomaterials for the adsorption of ions in aqueous solution was reviewed. Modification of graphite oxide or graphene and metal oxides, organic matter generated by the combination of different nano-materials, the adsorption capacity and separation efficiency have been greatly increased.
