摘　　要：土壤中重金属和有机物污染既造成巨大经济损失,又严重威胁人类健康。生物炭作为来源广泛、制备简单,比表面积大、表面官能团丰富、孔隙结构发达的材料,被广泛应用于农业、生态修复和环境保护领域。从生物炭的来源与制备工艺、对污染物的吸附机理、影响因素以及在土壤重金属和有机物污染修复中的应用现状等方面进行了综述,同时对生物炭材料在土壤污染修复中的研究重点进行了展望,为生物炭在土壤污染修复中的应用提供参考。The pollution of heavy metals and organic matter in soil not only causes huge economic losses,but also seriously threatens human health.Biochar is widely used in agriculture,ecological restoration and environmental protection because of its wide range of raw materials,simple preparation method,large specific surface area,rich surface functional groups and developed pore structure.In this paper,the source and preparation technology of biochar,the adsorption mechanism of pollutants,the influencing factors and the application status of biochar in soil heavy metal and organic pollution remediation were reviewed.at the same time,the research focus of biochar materials in contaminated soil remediation was prospected,in order to provide reference for the application of biochar in soil pollution remediation.Biochar is widely used in agriculture,ecological restoration and environmental protection because of its wide range of raw materials,simple preparation method,large specific surface area,rich surface functional groups and developed pore structure.In this paper,the source and preparation of biochar,the adsorption mechanism of pollutants,the influencing factors and the application status of biochar in soil heavy metal and organic pollution remediation were reviewed.Finally,the research focus of biochar materials in contaminated soil remediation was prospected,in order to provide reference for the application of biochar in soil pollution remediation.
