[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.
