【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。更多还原

【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.更多还原
