生物质炭对土壤中重金属形态和迁移性的影响及作用机制
Mechanism and effects of biochar application on morphology and migration of heavy metals in contaminated soil
摘要
Abstract
The applications of biochar, a pyrolytic product of biomass under the oxygen-free conditions, in im-proving soil fertility and other physicochemical properties as well as remediating heavy metal contaminated soil have become one of hotspots in the frontiers of environmental research. This paper reviewed the up-to-date pro-gresses of the research concerning biochar, in an attempt to illustrate the mechanisms related to the interactions between heavy metals and biochar, including physical adsorption, ionic adsorption and exchange, precipitation and complexation, by which the bioavailability, mobility, and biotoxicity of heavy metals in soil could be effec-tively reduced. However, there still exist some problems, especially regarding how to enhance the long-term stability of biochar in immobilizing the metal ions. Meanwhile, the consortium study concerning the biochar-soil-crops-human health is urgently needed in the near future.关键词
