| 摘 要： | 以201×7强碱性苯乙烯系阴离子交换树脂对水中苯酚进行吸附性能研究。详细研究了吸附体系中溶液的pH值、苯酚的起始浓度、树脂的投加量对吸附的影响,并将平衡数据用Langmuir和Freundlich方程进行对比分析。结果表明,吸附量随pH增大而增大,pH≥7时吸附量趋于恒定达到最大值;吸附量随着苯酚起始浓度的增大而降低,苯酚去除率随着树脂投加量的增加而增大;吸附过程更符合Langmuir模型。

| Abstract: | The adsorption capacity of phenol by strong alkaline styrene anion exchanged resin(201×7) was studied.The adsorption parameter,such as the initial pH value,concentration of phenol and the quantity resins added,was detailed investigated.Results showed that the highest adsorption increasing with the pH value,the higher concentration of phenol and the quantity of resins added.Adsorption process was well described both Freundlich equation. |
