【摘要】：生物质炭是生物质原料在缺氧条件下经高温裂解而成的一种固体产物,它们在土壤重金属污染修复中的应用是当前环境研究的热点之一。对目前生物质炭研究的进展进行了综述,阐明了生物质炭施入土壤可通过物理吸附、离子吸附、离子交换、沉淀络合等交互作用机制,显著降低土壤重金属的有效态,减少它们在环境介质中的迁移性,从而降低土壤重金属的生物毒性。但是生物质炭的研究仍然存在许多问题,特别是如何增强它们在土壤环境中对重金属离子钝化的稳定性、长效性以及生物质炭—土壤—作物—人体健康风险一体化研究等方面,仍需要持续深入研究。
[Abstract]:Biomass charcoal is a kind of solid product formed by pyrolysis of biomass raw material under anoxic condition at high temperature. Its application in remediation of heavy metal pollution in soil is one of the hot spots in the field of environmental research. The research progress of biomass carbon was reviewed in this paper. The mechanism of interaction between biomass carbon and soil, such as physical adsorption, ion exchange, precipitation complexation and so on, was expounded, and the effective state of heavy metals in soil was significantly reduced. Reduce their migration in environmental media, thereby reducing the bio-toxicity of heavy metals in soil. However, there are still many problems in the research of biomass carbon, especially how to enhance the stability of heavy metal ion passivation in soil environment, the long-term efficiency and the integrated research of biomass carbon-soil-crop-human health risk, and so on. There is still a need for continued and in-depth research.
