中文摘要：

采用浸润法制备活性炭负载亚铁离子复合材料（GAC-FeCl2），利用扫描电镜（SEM）对GAC-FeCl2、GAC进行表征。考察了不同pH值和初始浓度下对PFOA的去除效率，并用吸附等温模型和动力学模型进行拟合，探讨其去除机理。结果表明，活性炭负载亚铁离子复合材料（GAC-FeCl2）对PFOA的去除效果较好，PFOA的去除率在酸性条件下较好，吸附等温实验表明，Langmuir模型能更好地描述其对PFOA的等温吸附过程；吸附动力学实验表明，吸附剂对PFOA的反应过程更符合准二级吸附动力学方程。

英文摘要：

Fe^2＋ salts supported on activated carbon （GAC-FeC12 ） was synthesized in infiltration, the GAC-FeC12 and GAC-FeC12were characterized through scanning electronic microscopy （SEM）. Examines the removal efficiency of PFOA under different pH and initial concentration reaction conditions. And it was fitted by adsorption isotherm and kinetic model, and assessed its removal mechanism. The results shows that the effect of removal of PFOA is the best with FeC12 supported on activated carbon, the removal rate of PFOA under the acid condition is better. Adsorption isotherm experiments shows that Langmuir model is better describing the composite material adsorption of PFOA process. Adsorption kinetics result shows that the adsorption of PFOA of composite material （ GAC-FeC12 ） is more in line with the pseudo- secondary dynamics equation.
