摘要
采用化学还原的方法制备石墨烯氧化物,并将其负载在聚吡咯上,通过XRD、SEM、TEM、Raman、TGA等手段表征其结构。将其应用于系列金属离子水溶液的吸附试验,发现其对Hg2+具有很好的吸附选择性和吸附量,并且该石墨烯氧化物材料在经过酸处理后还能循环利用,这为含Hg2+废水的处理提供了一种潜在的方法。
Graphene oxidem was prepared by chemical reduction and was loaded on polypyrrole, through XRD, SEM, TEM, Raman, TGA and other means characterizing its structure. It was applied to series of metal ions in aqueous solution assay, and found that it had good adsorption selectivity and adsorption capacity on Hg^2+, and that the graphene oxide materials can be recycled after acid treatment, which provides a potential method for wastewater treatment with Hg^2+.
