土壤和沉积物中多环芳烃的界面吸附研究进展

Research advances in PAHs adsorption on soil-sediment interface

综述了环境中多环芳烃的危害、来源及分布,并在此基础上重点介绍了多环芳烃在土壤和沉积物中界面作用的常见作用模式,包括线性分配模型和非线性吸附模型及其应用;多环芳烃疏水性有机物吸附的影响因素,主要有土壤和沉积物中含碳物质的结构类型以及多环芳烃本身的分子特性。最后提出本领域研究中的建议与展望。

This paper summarized the harm, source, and distribution of PAHs in the environment, and introduced in stress the general action modes （including linear and nonlinear allocation models） of PAHs on soil-sediment interface and their applications. The main factors affecting the adsorption of hydrophobic PAHs pollutants were the structure and composition of the organic matters in soil and sediment, and the molecular characters of PAHs. Suggestions and expectations on further research in this field were put forward.
