摘要
通过静态实验,研究了凹凸棒复合吸附剂对苯酚的吸附性能和影响吸附效果的相关因素。实验结果表明,凹凸棒复合吸附剂对苯酚的吸附过程遵循准二级动力学模型,吸附等温线符合Langmuir方程,温度和pH变化对吸附行为没有显著影响,吸附为放热的物理吸附过程。吸附剂再生后可以反复使用。
Experiment was conducted on adsorption characters and influence factors of attapulgite composite ad- sorbent. The results showed that the adsorption reaction followed pseudo-second-order-rate equation and fitted with Langmuir isotherm. Adsorption rate changed little with variation of temperature and pH. Adsorption was physical exothermic process. Attapulgite composite filter material had high recycling rate after regeneration.
