| 摘 要： | 测定了水相中苯胺在NKA-II和AB-8这2种大孔吸附树脂上的吸附等温线和吸附速率曲线.结果表明:极性的NKA-II对苯胺的吸附量要高于弱极性的AB-8对苯胺的吸附量,苯胺在2种吸附树脂上的相平衡关系符合Freundlich方程;苯胺在NKA-II和AB-8上的吸附受膜扩散控制.动态吸附实验和模拟结果表明:模拟透过曲线与实验透过曲线比较吻合,所建立的模型能够较好地描述苯胺在2种大孔吸附树脂填充柱上的吸附透过过程.

| Abstract: | The adsorption isotherms and kinetics of aniline on NKA-II and AB-8 macroporous adsorp-tion resin were investigated.The results showed that the experimental isotherms of aniline on the two resins were satisfied with Freundlich equation.Aniline adsorption quantity on NKA-II was higher than that on AB-8.The adsorption rate-limited step of aniline on the two resins was controlled by film diffusion.The dynamic experiment and theoretical simulation results showed that the simulation breakthrough curves were in good agreement with the experimental breakthrough curves. |
