| 摘 要： | 研究了大孔吸附树脂NDA—909吸附水溶液中邻甲酚的热力学特征，并与Amberlite XAD—4树脂进行了比较．通过吸附动力学实验，初步探讨了初始温度对吸附过程的影响。结果表明，NDA—909对邻甲酚的吸附符合Freundlich经验公式，表现为放热的物理吸附过程．此外吸附速率受颗粒内扩散和其它类型扩散的共同控制。

| Abstract: | A comparison study was made on the adsorption behaviors of o-cresol onto the macroporous adsorbent NDA-909 with that on the Amberlite XAD-4, including the static equilibrium adsorption, the adsorption thermodynamics properties and so on. In addition, study on adsorption kinetics of o-cresol on NDA-909 was also carried out through static experiments. The effect of initial temperature on o-cresol sorption was evaluated. The results showed that the adsorption date fit well into the Freundlich isotherm, and the uptake of o-cresol on NDA-909 was a type of physical adsorption. Besides, the rate of adsorption was under the control of intra-particle diffusion and external diffusion simultaneously. |
