摘　　要：针对土壤重金属污染问题已有许多修复措施,生物炭由于其特殊的结构、良好的经济效益成为了近年来土壤修复领域的研究热点。生物炭作用于土壤重金属的相关机理复杂,且施入土壤会对重金属的环境行为产生影响。简述了目前生物炭在环境保护领域中的相关应用,在如离子交换、表面络合、沉淀作用以及阳离子-π作用等基础上分析了生物炭作用于重金属的机理,并介绍了生物炭对于土壤中重金属迁移性和生物有效性的影响。对生物炭今后的研究工作作出展望。There are many remedial measures for the problem of heavy metal pollution in soil,biochar has been a hot area of research in the field of soil remediation in recent years because of its special structure and good economic benefit. The mechanisms of biochar act on heavy metals in soil is complex,and the biochar added into soil will have an impact on the environmental behavior of heavy metals. The application of biochar in the field of environmental protection is sketched,the mechanisms of biochar are analyzed on the basis of the effects such as ion exchange,surface complexation,precipitation and cation-π,and the effects of biochar on mobility and bioavailability of heavy metals in soil are also introduced. Finally,the future research work of biochar is prospected.
