| 摘 要： | 以花生壳为原料所制备的活性炭对酚有良好的吸附能力,实验测定了苯酚、对硝基苯酚在活性炭上的吸附特性.结果表明,两种酚在活性炭上的吸附等温线可用Freundlich或Langmuir等温式分析,吸附动力学曲线可用假一级或假二级动力学模型拟合.在苯酚与对硝基苯酚的混合溶液中,当活性炭投加量不足时,两种酚之间存在竞争吸附机制,对硝基苯酚的吸附平衡常数大,因而优先吸附,混合酚的总吸附量与总平衡浓度、吸附时间的关系与单一酚溶液中的吸附类似.

| Abstract: | Activated carbon derived from peanut hull is an excellent adsorbent for phenols removal.The adsorption of phenol and 4-nitrophenol on the activated carbon was investigated.It was shown that the adsorption isotherms follow the Freundlich or Langmuir models.The kinetic data were fitted to follow the pseudo-first-order or pseudo-second-order models.Competitive adsorption was observed in the mixture of phenol and 4-nitropheno in the case of insufficient dosage of adsorbent.And 4-nitropheno was preferentially ad... |
