摘要
为探究氧化石墨烯(GO)对PM2. 5的吸附性能,采用喷涂方式,制备了以4种不同无纺布为基底的GO薄膜,测试了其吸附性能及薄膜长效性。采用扫描电镜、拉曼光谱、X射线衍射及红外光谱进行表征。结果表明:GO成功附着在无纺布纤维表面及纤维间形成薄膜,并且GO材料存在对PM2. 5的吸附性且效果明显。不同基底上GO薄膜去除率分别约为34%、95%、45%及82%,提高了27%、5%、30%及28%。经过15d的连续测量,GO薄膜对PM2. 5的去除保持了良好的稳定性及长效性。
In order to investigate the adsorption properties of graphene oxide(GO) on PM2. 5,GO films based on four different non-woven fabrics were prepared by spraying method,and their adsorption properties and long-term effectiveness were tested. The samples were characterized by scanning electron microscopy,raman spectroscopy,X-ray diffraction and Infrared spectroscopy. The results shown that GO was adhered to the surface of the non-woven fabric and formed a film between the fibers. The GO material had the adsorption property to PM2. 5 and the effect was obvious. The GO film removal efficiency on different substrates were 34%,95%,45%,and 82%,respectively,which increased by 27%,5%,30%,and 28%. After 15 days of continuous measurement,the removal of PM2. 5 by GO film maintained good stability and long-term effectiveness.
