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 be pseudo-second order equation. As adsorption temperature increased

adsorption rate constant and initial adsorption rate tended to increase. Based on the above-mentioned results

some guidance may be provided for the adsorption removal of organic chlorides from naphtha.
