| 摘 要： | 采用邻羧基苯甲酰基修饰的吸附树脂FZH5,以Amberlite XAD-4作为参照,探讨了对水溶液中2-萘酚的吸附热力学和吸附动力学。分别用Langmuir等温方程和Freundlich等温方程对吸附等温线进行拟合,并采用动力学准一级和二级方程对两种树脂进行了动态吸附拟合。结果表明,经过修饰的FZH5对水中2-萘酚的吸附效率高于Amberlite XAD-4,对2-萘酚的吸附过程在温度较高时化学吸附为主导,吸附速率主要受控于颗粒内扩散过程。

| Abstract: | Compared with that of Amberlite XAD-4 resin,the adsorption thermodynamics and adsorption kinetics of 2-naphthol in aqueous solution were studied with the adsorbent named FZH5 modified with 2-carbonylbenzoyl group on chloromethylcated styrene-divinylbenzene.Two isotherm models(Langmuir and Freundlich) were used to fit the static adsorption results and the pseudo-first-order equation and pseudo-first-order equation were used to fit the kinetics data.The results show the adsorption efficiencies of 2-naphthol onto FZH5 are higher than those of XAD-4,which attributes to the chemical transition between 2-carbonylbenzoyl group in FZH5 and the phenolic hydroxyl group in 2-naphthol at higher temperature.And the intraparticle diffusion plays a dominant role in the adsorption of 2naphthol onto two adsorbents studied. |
