摘　　要：本文采用沉淀法成功合成了Fe(Ⅲ)掺杂的ZIF-67,采用XRD、BET、SEM、XPS、FT-IR对样品进行了表征,并考察了ZIF-67及Fe/ZIF-67对甲基绿的吸附效果。结果表明,7%Fe/ZIF-67对甲基绿染料表现出优越的吸附性能,60 min内可以将100 mg·L^(-1)甲基绿溶液完全去除,优于纯ZIF-67。其吸附行为符合准二级动力学模型和Langmuir等温模型。In this paper,Fe(Ⅲ)-doped ZIF-67 was successfully synthesized by the precipitation method.The samples were characterized by XRD,BET,SEM,XPS and FT-IR,and the adsorption effect of ZIF-67 and Fe/ZIF-67 on methyl green was investigated.The adsorption experiments showed that 100 mg·L^(-1) methyl green solution could be completely removed by 7%Fe/ZIF-67 within 60 min,which is better than by pure ZIF-67.The adsorption process conforms to the Langmuir isotherm adsorption model,and the adsorption kinetics conforms to the pseudo-second-order kinetic model.
