| 摘 要： | 生物质炭是生物质废弃物在限氧条件下热解产生的多孔、低密度的富碳材料。前体物质和热解条件在很大程度上决定了生物质炭的表面积和阳离子交换量,影响生物质炭将重金属污染物吸附到其表面的能力,从而影响重金属在农田土壤中的迁移。本文从生物质炭的前体物质种类及热解条件对生物质炭的特性、改良土壤以及修复重金属污染农田土壤的影响等方面进行综述,并提出生物质炭修复重金属污染农田土壤研究的未来发展趋势。

| Abstract: | Biochars are carbon-rich and low-density materials which are pyrolyzed under limited oxygen atmosphere. The surface areas and cation exchange capacities are largely determined by precursors species and pyrolysis conditions, which influence adsorption capability of biochars of heavy metals onto the surface, reducing the migration of contaminants in agricultural soils. We reviewed effects of precursors species and pyrolysis conditions on characteristics, amelioration of soil and its immobilization on heavy metals in the soil. Furthermore, the future research direction in the remediation of heavy metals by biochar in agriculture soil was suggested. |
