| 摘 要： | 通过静态吸附实验，研究了1,2-二氯苯在吸附剂N上的吸附热力学和动力学。研究结果表明，1,2-二氯苯在吸附剂N上的吸附等温线属于典型的S型吸附等温线，可用Freundlich吸附等温方程进行描述，吸附可自发进行，且为放热过程，属于物理吸附；1,2-二氯苯在吸附剂N上的吸附动力学可用拟二级动力学方程较好地描述，吸附温度越高，吸附速率常数和初始吸附速率越大。该研究可为石脑油中有机氯化物的吸附脱除提供指导。

| Abstract: | The thermodynamics and dynamics of 1,2-dichlorobenzene adsorption on adsorbent N were investigated via the static adsorption experiments.The experimental results demonstrated that the adsorption isotherm of 1,2-dichlorobenzene adsorption on adsorbent N was S type,and Freundlich adsorption equation could describe the adsorption process well.The thermodynamic parameters illustrated that the adsorption was a spontaneous and exothermic process,belonging to physical adsorption.The adsorption dynamics appeared to... |
