| 摘 要： | 以粉末活性炭为吸附剂，采用批式试验，研究静态吸附对黄连素脱铜废水中Cu2+的去除效果，分析了吸附剂投加量(5～50 g/L)，pH(1.0～5.0)和接触时间(20～600 min)对吸附效果的影响. 当pH为2.4，吸附剂投加量为30 g/L时，反应300 min即可达到吸附平衡状态. 通过对吸附动力学和吸附等温线的模型分析发现，二级吸附动力学模型能够更好地描述试验结果，对吸附平衡数据的拟合采用Langmuir吸附等温线优于采用Freundlich吸附等温线.

| Abstract: | The removal efficiency of Cu2 + static adsorption from berberin wastewater by powdered activated carbon was studied in a batch adsorption system.Factors affecting copper ion adsorption,such as pH(1.0-5.0),adsorbent dosage(5-50 g /L) and reaction time(20-600 min),were investigated.When the pH was 2.4 and the adsorbent dosage was 30 g /L,the equilibrium of the adsorption process was established in about 300 min.A comparison of kinetic models and isotherm models of adsorption showed that the adsorption system was better described by a second-order adsorption kinetic model.The adsorption equilibrium data fit better with the Langmuir isotherm than with the Freundlich isotherm. |
