| 摘 要： | 研究活性白土对苯酚的等温吸附特性,考察了初始溶液浓度、活性白土粒径、pH值、温度4种因素对吸附作用的影响,并分析了不同条件下活性白土吸附苯酚的动力学过程.结果表明: Langmuir等温方程能较好地描述活性白土对苯酚的等温吸附特征; 初始溶液浓度越高,活性白土对苯酚的吸附量越大; 随着活性白土粒径的减小,其对苯酚的吸附量增大; 碱性条件有利于活性白土对苯酚的去除; 吸附动力学过程符合准二级动力学模型.

| Abstract: | The adsorption kinetics performance on adsorption of phenol in wastewater onto activated clay is studied.The effects of initial concentration,particle sizes,pH values and temperature on adsorption are investigated and the adsorption kinetics process of phenol onto activated clay is also analyzed under different conditions.The results show that isothermal Langmuir equation can describe the isothermal adsorption characteristics of phenol on activated clay well.Both high initial concentration and small the par... |
