摘要 研究了坡缕石-壳聚糖负载环糊精-活性炭对苯酚、对苯二酚的吸附行为,测定了酸度、吸附剂投加量、溶液浓度、温度等因素对吸附性能的影响.吸附热力学表明随着温度的升高,吸附容量下降,吸附过程可以用Langmuir等温吸附模型进行较好的模拟. The adsorption behavior of phenol and hydroquinone on the adsorbent of palygorskite-chitosan supported cyclodextrin-actlvated carbon is studied. The effects of acidity, amount of the adsorbent, concentration of phenolic compounds and the temperature on the adsorption are examined. Thermodynamic studies show the adsorption capacity of the adsorbent decreases with the increasing of the temperature. The adsorption process can be simulated by the Langmuir isothermal equation well.
