摘要
在土壤重金属防治中,生物炭因其特有结构和性质,可降低土壤重金属活性和移动性,减少土壤中重金属生物有效性,达到修复重金属污染土壤目的。文章综述近年来国内外有关生物炭修复土壤重金属研究进展,阐述生物炭对土壤重金属生物有效性、重金属形态、重金属迁移转化等方面影响,分析作用机理并提出展望。
Due to the special structure and properties of biochars, it was applied for heavy metal contaminated soils. Biochars can effectively reduce the activity and mobility of heavy metals, lessen bioavailability of heavy metals in contaminated soils. A review summarized the present researches about the application of biochars on heavy metal contaminated soils, especially for the influence of biochars on the bioavailability, speciation, migration of heavy metals in soils and the analysis of mechanism. In the end, the paper analyzed the deficiency and prospects of future research.
