以多环芳烃荧蒽为研究对象，通过模拟吸附实验，研究了嘉陵江重庆段底泥对荧葸的吸附特性及其机理，进一步探讨了离子强度、pH值及腐殖酸（HA）对吸附性能的影响。结果表明：嘉陵江底泥对水体中荧葸的吸附曲线较好地符合传统的线性分配模型和Freundlich等温吸附模型。随着pH值增加，荧蒽在底泥上的吸附容量减小；离子强度的增大有利于荧蒽在底泥上的吸附；腐殖酸的加入显著增强了荧葸在底泥上的吸附能力，其吸附系数与腐殖酸含量呈线性正相关。

Experiments were carried out to investigate characteristics and mechanism of sorption of fluoranthene on surface sediment in the Jialing River. Moreover, impacts from pH value, ionic strength and Humic acid（HA）on the sorption experiments were assessed as well. Results suggest that the sorption curve of fluoranthene on surface sedi- ment was in line with the traditional linear partition model and Freundlich sorption model. The adsorption capacity of surface sediment to fluoranthene was declined along with increase in pH value, while increase in ionic strength ap- pear to facilitate sorption of fluoranthene on surface sediment;similarly, growing HA level significantly increased adsorption capacity. The association between partition coefficient and HA prove to be positively linear correlated.
