摘　　要：对取自富水水库渗滤水的悬浮物进行了分析、表征,表明其主要成分为针铁矿(-αFeOOH);通过静态吸附实验研究了该悬浮物对五氯苯酚(PCP)的吸附性能,并考察了pH值、离子强度以及十二烷基苯磺酸钠(Las)等环境因子对吸附性能的影响。结果表明,该悬浮物对PCP有较好的吸附效果,吸附平衡时间为2.5 h;吸附行为符合Freundlich型等温线;pH=6时吸附量最大。The paper analyzed and characterized the suspended matter in the percolating water of Fushui reservoir. It indieated that the main composition of the suspended matter was goethite （a-FeOOH）. Batch adsorption isotherm experiments of pentachlorophenol （PCP） on the suspended matter were carried out in this paper. Furthermore, the effects of the pH value, ionic strength and the anionic surfactant Sodium dodecylbenzene sulfonate （Las） on the adsorption behaviors of PCP were also researched, The results indicated that the adsorption characteristics of PCP on the suspended matter followed Freundlich isotherm equation. It needed 2.5 hours to reach balance of absorption, and the absorptive capacity became the maxium when the pH value was 6.
