摘　　要：为掌握多孔介质中铁的吸附特征及其运移规律,采用室内静态吸附实验和数值模拟的方法,研究不同吸附模式下的铁在多孔介质中的运移规律。由室内静态吸附实验得到研究区浅层多孔介质对铁的吸附特征,通过相关性分析得到Langmuir等温吸附方程的相关系数最高,多孔介质对铁的吸附更符合Langmuir吸附模式。模拟计算铁在地下水中的浓度分布情况,得到不同吸附模式下的铁在地下水中的运移规律。此成果对研究多孔介质中铁的运移规律具有一定的参考价值及指导意义。In order to reveal the adsorption characteristics and transport laws of fe in porous media,research on transport laws of Fe under different adsorption model was conducted by means of the laboratory static adsorption experiments and numerical simulation. Adsorption characteristics of Fe in shallow porous media of study area were gotten by laboratory static adsorption experiments. Langmuir isotherm equation had the highest correlations according to correlation analysis,indicating Langmuir adsorption mode was more accordant with the adsorption of Fe in porous media. A simulating computation was conducted for concentration distribution of Fe in groundwater. Results showed transport laws of Fe under different adsorption mode. These results could provide some reference and guidance for research on the migration of iron in porous media.
