摘要
生物炭在改良土壤、固碳与环境修复等方面的良好特性使其成为农业和环境保护领域的研究热点。然而由于生物炭的稳定性强、比表面面积大,施用到土壤后会改变原有的土壤环境,影响重金属在土壤中的环境行为。本文就生物炭制备、特性、土壤重金属的稳定化机制及影响因素进行综述,在此基础上,对生物炭在土壤中的环境行为及归趋、重金属污染土壤的生物炭修复机理及环境效应、生物炭前体物的环境风险与生物炭作为负载材料等方面进行了展望。
The application of biochar in improving soil quality, carbon sequestration and environmental remediation has been a hotspot in environmental protection researches for its good performance. Biochar is stable with large specific surface area, therefore changing the initial soil environment and regulating the behavior of soil heavy metal. In this article, the characteristics of biochar, the mechanism in stabilizing soil heavy metal and the influencing factors are reviewed. On the basis of that, prospects have also been made for biochar in terms of its environmental behavior and fate, the mechanism involved in soil heavy metal remediation,environmental impacts, and the potential risk of being chemical precursors as well as the potential of being load material.
