| 摘 要： | 研究并比较了四种大孔吸附树脂对正庆烷中低浓度苯、甲苯的吸附平衡及动力学。Langmuir方程能够良好地描述吸附等温线，由单组分吸附平衡得到的参数；可以很好地预测双组分吸附平衡。动力学研究表明，内扩散过程是决速步，并估算出粒内扩散系数。

| Abstract: | The equilibria and kinetics of benzene and toluene adsorption by four macroporous adsorption resins were studied. The Langmuir's equation was suggested to describe the adsorption isotherms of monocomponent. Based on the monocomponent adsorption isotherms and material balance, two-component competitive sorption isotherms can be successfully predicted. The kinetic experiments showed that the particle diffusion was the rate-controllillg step and the diffusion coefficient was calculated. |
