| 摘 要： | 通过静态和动态吸附法研究了2-萘酚在α-甲基吡啶修饰的大孔聚苯乙烯树脂(Mpy)上的吸附行为,并与Amberlite XAD-4树脂的吸附行为进行比较,探讨了树脂结构和化合物性质对吸附行为的影响.结果表明,Freundlich和Langmuir方程很好地拟合了2-萘酚在Mpy树脂上的吸附行为,2-萘酚在Mpy树脂上的吸附过程存在化学作用,为一级动力学吸附.

| Abstract: | New polymeric adsorbent modified withα-methylpridine(Mpy) for adsorbing 2-naphthol was prepared.The static adsorption and kinetic characteristics for 2-naphthol onto Mpy and Amberlite XAD-4 at different temperature were studied and their adsorption mechanism were further investigated.The result shows that chemical interaction will be in existence in the adsorption process of 2-naphthol in aqueous solutions with Mpy modified chemically and the adsorption process was fit for the first order kinetics equation. |
