摘要
为了提高纳米零价铁对污染物的吸附和还原性能,采用气溶胶辅助制得碳载纳米零价铁(Fe/C),并通过对Fe/C硫化改性制备得到改性材料(S-Fe/C),采用扫描电子显微镜(SEM)、透射电子显微镜(TEM)、X射线衍射分析(XRD)、X射线光电子能谱(XPS)等多种方法对材料进行表征,考察了S-Fe/C的材料特征。探究了该材料对孔雀石绿(MG)的吸附性能以及对三氯乙烯(TCE)的还原性能。结果表明,S-Fe/C对MG的吸附量达到1663 mg/g,对TCE 10 h去除率为85.57%,表明S-Fe/C具有良好的吸附性能和还原性能。
In order to improve the adsorption and reduction performance of zero-valent iron nanoparticles on pollutants,the carbon-loaded zero-valent iron nanoparticles(Fe/C)were prepared by aerosol-assisted fabrication,and the modified material(S-Fe/C)was prepared by sulfurizing and modifying Fe/C.The material characteristics were investigated by various methods,such as scanning electron microscope(SEM),transmission electron microscope(TEM),X-ray diffraction(XRD),X-ray photoelectron spectroscopy(XPS),etc.The material characteristics of S-Fe/C were also investigated,and the material characteristics of S-Fe/C were investigated.The adsorption properties of the material towards malachite green(MG)and the reduction properties towards trichloroethylene(TCE)were explored.The results showed that the adsorption of MG by S-Fe/C reached 1663 mg/g and the removal rate of TCE for 10 h was 85.57%,indicating that S-Fe/C has good adsorption and reduction properties.
