【摘要】 用静态吸附法考察了一种活性炭对废水中四种简单芳香化合物的吸附行为,并用Langmuir模型对吸附数据进行了拟合。结果表明,Langmuir模型可以近似地描述这些芳香化合物在该活性炭上的吸附行为。芳香化合物的极性及其在水中的溶解度对其在活性炭上吸附的影响较大,芳香化合物与活性炭之间的π-π色散作用对吸附的影响很小。更多还原

【Abstract】 Adsorption behavior of a number of aromatic compounds on an activated carbon was investigated in static state system,and the adsorption data were fitted using Langmuir model.It is found that adsorption behavior of aromatics on activated carbon is approximately described by Langmuir model,solubility and/or polarity of the compounds have major influences on the adsorption,and π-π dispersion interaction plays little role in the adsorption.更多还原
