| 摘 要： | 采用现场采样、室内分析方法,研究了菲在西湖底泥中的吸附／解吸行为。结果表明,菲在西湖底泥中的吸附和解吸速率都较快,均能在8h内达到平衡。菲的吸附等温线为“S”形,能较好地符合Freundlich方程,说明西湖底泥有不均匀的外表面。其连续吸附／解吸曲线为阶梯形,有明显的不可逆吸附现象,是由于底泥中高含量的有机质造成的。

| Abstract: | Sorption /desorption properties o f phenanthrene on sediment in West Lake were studied.Both sorption and desorption can reach equilibriumin less than 8hour s.Under the conditions of the presen t experiment,the sorption of phenan threne on sediment was characterized by"S"isothermand may be well described by Freundlich equation.It was reflected that there was symmetrical surface in the sediment.It was found that the cu rves of multi -step sorption /desorp tion experiments were step -wise and phenanthrene irre-versibly adsorbed onto the sediment .It may be explained that the irreversible sorption was caused by the high content of organic matters in the sediment. |

| Keywords: | polycyclic aromatic hydrocarbon(PAH) phenanthrene sediment sorption |
