| 摘 要： | 通过静态吸附和动态吸附法研究了水杨酸修饰的超高交联吸附树脂(SYS树脂)对苯酚的吸附行为,实验静态数据分别用Langmuir、Freundlich和Dubinin-Radushkevich等温方程拟合,动态数据用准一级动力学和准二级动力学模式拟合。结果表明,SYS树脂在一定的温度下对苯酚既存在物理吸附又存在化学吸附,吸附过程为一级动力学吸附过程。

| Abstract: | Hypercrosslinked polymeric adsorbent modified with salicylic acid(SYS) for adsorbing phenol was prepared.The static adsorption and kinetic characteristics for phenol onto SYS were investigated.Three adsorption equations were employed to fit the static data.The first order kinetics equation and the second order kinetics equation were employed to fit the dynamic data.The result shows that physical adsorption and chemical adsorption exist in the adsorption processes of SYS resin for phenol at the right temperature.The adsorption process was fit for the first order kinetics equation. |
