%X 改性多孔材料因其高性价比与优良的孔隙结构和比表面积等性质，被广泛应用于重金属污染土壤修复领域。综述了改性多孔材料修复单一及复合重金属污染土壤特性，分析了材料性质、施用量和土壤环境等因素对其修复效率的影响。从改性多孔材料物理吸附、静电作用、表面配位、离子交换、氧化还原和沉淀作用方面介绍了改性多孔材料钝化重金属的可能机制。提出了改性多孔材料在制备与应用过程中可能存在的不利影响及待解决的问题。以期为改性多孔材料在土壤修复领域的应用推广提供有益参考。<br />
Modified porous materials have been widely used in heavy metal contaminated soil remediation because of their high cost performance and excellent pore structure and surface area. The proper-ties of modified porous materials for the remediation of single and composite heavy metal con-taminated soil were reviewed, and the effects of material properties, application amount and soil environment on the remediation efficiency were analyzed. The possible mechanism of passivation of heavy metals by modified porous materials was introduced in terms of physical adsorption, elec-trostatic interaction, surface coordination, ion exchange, REDOX and precipitation. The possible adverse effects and problems to be solved in the process of preparation and application of modified porous materials were put forward, in order to provide useful reference for the application of modified porous materials in the field of soil remediation.
