摘要
生物炭是由废弃生物质在缺氧条件下热解而成的一种含碳丰富的产物。由于具有精细的孔隙结构和独特的表面特性,生物炭对重金属污染物有着良好的吸附能力,从而影响污染物的迁移。从生物炭的基本特性、吸附机理以及对土壤中重金属的修复效果等方面进行综述,最后提出生物炭未来在环境修复方面的研究方向。
Biochar is the product of thermal degradation of waste biomass under the limit-oxygen condition,which is made up of abundant carbon. Biochar has the efficient absorption of heavy metal due to its precise pore structure and unique chemical properties,so that it can influence the transfer of heavy metal. It was summarized some characteristics of biochar,the mechanism of absorption and its immobilizing effect on heavy metal in the soil. At last,the future research direction in the environmental amendment was suggested.
