摘要
生物炭是一种废弃物资源化利用的产物。作为新型环境功能材料,生物炭以其优良的环境效应和生态效应成为环境科学等学科研究的前沿热点。因其孔隙结构发达、比表面积巨大和独特的表面化学性质,对环境介质中的重金属离子有很强的吸附作用,进而影响了重金属离子的迁移与归宿。主要从生物炭的材料来源、吸附重金属离子的机制、影响因素以及对土壤中重金属生物有效性的影响等方面进行综述,并提出生物炭吸附重金属离子的未来研究方向。
Biochar is the product of waste reutilization.As a new type of environment function material,biochar has become the forefront hotspot of environmental science and other disciplines because of its excellent environmental effects and ecological effects.Biochar has functions of strongly adsorbing heavy mental because of its developed pore structure,huge surface area and unique surface chemical properties and further affecting the transfer and fate of heavy metals.This article mainly summarizes from material source of biochar,mechanism and influencing factors of heavy metals adsorbed by biochar,and the effects of biochar on the bioavailability of heavy metals in soil and so on.Finally, the article puts forward the future research directions on sorption of heavy metals by biochar.
