摘要
在土壤中,有机质是重要的组成部分。它通过其含有的大量含氧官能团及其他官能团与土壤中重金属之间的离子交换吸附、络合、螯合等一系列反应抑制或促进重金属在土壤中的吸附,从而影响重金属的沉淀、迁移转化和生物有效性,甚至影响生态环境安全和人类健康。由于土壤有机质组成复杂,其作用机制及其作用效果很难完全研究清楚。因此,笔者在前人的基础上,综述了有机质对土壤吸附重金属的影响及其机理的研究进展。
Organic matter is an important component in soil. It inhibits or promotes the adsorption of heavy metals in the soil through a series of reactions such as adsorption, complexation, chelation and so on by the ion exchange adsorption, complexation and chelating of the large number of oxygen-containing functional groups and other functional groups and heavy metals in the soil, thus affecting the precipitation of heavy metals, And bioavailability, and even affect the ecological and environmental health and human health. Because of the complex composition of soil organic matter, its mechanism and its effect are difficult to study completely. Therefore, on the basis of predecessors, the author reviewed the progress of organic matter on the adsorption of heavy metals and its mechanism.
