摘要:
为改善氧化石墨的吸附性能,进一步拓展其在废水处理领域中的应用,该文以氧化石墨(GO)作为基体构筑新型的复合材料。通过回流冷凝方法,将SnO2负载于GO表面,获得氧化石墨-氧化锡(GO-SnO2)复合材料。通过X射线衍射、扫描电镜及比表面分析等手段对产物进行了表征,结果表明:在合成过程中,GO的结构被彻底剥离为GO薄片,SnO2纳米小颗粒均匀负载于GO薄片表面。以甲基橙为模型体系,考察了GO基复合材料的吸附性能。负载SnO2后,GO的吸附性能明显提高,GO-SnO2在10 min内对20 mg/L的甲基橙的吸附去除率达到99.9%。
Abstract:
Graphite oxide(GO)is taken as the substrate to fabricate a novel kind of GO-based composite materials to improve its superior adsorption and expand its application in the waste water disposal field.Graphite oxides-tin oxide(GO-SnO2)composites are fabricated through refluence-condensation loading technique by loading SnO2 on GO.The obtained composite materials are characterized by X-ray diffraction,scan electron microscopy and Brunauer-Emmett-Teller measurements.The results show that GO is entirely exfoliated into single flake during the synthetic process,and SnO2 nanoparticles are loaded onto the single GO piece evenly.Adsorption removal of methyl oranges is used as the model system to investigate the adsorption properties of GO-based composites.After loading SnO2,the adsorption property of GO is improved greatly.The removal of methyl oranges(20 mg/L solution)is up to 99.9% within 10 min using GO-SnO2 as the absorbant.
