摘    要:以黄浦江底泥作为悬浮物,研究多环芳烃(菲)在天然水体中悬浮物上的吸附机理,结果表明:由甲醇作助溶剂的水溶液中,菲在黄浦江底泥上的吸附为多分子层吸附,可用BET等温吸附模式模合,吸附速率较快,助溶剂中甲醇对菲存在竞争吸附,膜扩散为菲在黄浦江底泥上吸附速度的控制步骤,这些均与菲的分子结构与特性有关。

关 键 词:多环芳烃  底泥  吸附  黄浦江  污染控制

Abstract:The sediment in Huangpu River was chosen as the suspended solids and of phenanthrene was a model compound of PAHs in this study. The mechanism for the adsorption phenanthrene on sediments in natural water was found. The results show that the adsorption of phenanthrene on sediments is of multi molecular layers one, which can be well described by BET model. The competitive adsorption is occurrence between methenol and phenanthrene. Film diffusion is the controlling step for adsorption rate in the adsorption process of phenanthrene on sediments. These are all related to the structure and properties of phenanthrene in comparing with other PAHs.
Keywords:PAHs  sediment  adsorption  BET adsorption model
