Static Adsorption Mechanism of Naphthalene on Carbonaceous Sorbents

  • 摘要: 通过分析考察试验吸附等温线与Langmuir,BET和Freundlich模型的拟合结果,以及吸附剂的结构参数(比表面积、总孔容积、平均孔径),对萘(Nap)在3种活性炭吸附剂上的静态吸附行为进行了研究.结果表明:3种活性炭吸附剂对萘均表现出良好的吸附能力(吸附量最高可达0.231 1 g/g),改性后活性炭颗粒吸附性能要明显优于原活性炭;萘在活性炭颗粒(AC-a,AC-c)和活性炭粉末(AC-b)上的吸附行为存在差异,在活性炭颗粒上表现为单分子层吸附的过程,而在具有突出比表面积的活性炭粉末上,吸附过程表现出多分子层吸附的特征.Langmuir和BET模型可以分别对萘在活性炭颗粒和粉末上的静态吸附行为进行合理的预测.
