摘　　要：研究了微波处理废触媒制备的活性炭对苯和甲苯的吸附性能。首先测定了20、30和40℃苯在活性炭上的吸附等温线,采用Langmuir方程对实验数据进行处理,然后以苯的吸附等温线数据为依据,应用Polanyi吸附势论预测了甲苯在活性炭上的吸附等温线。实验数据和计算数据最大偏差仅为6%和5.55%,说明预测结果是有效的。The adsorption capability of benzene and toluene in regenerating activated carbon doped ZnO by microwave heating was investigated.The adsorption isotherms of benzene at temperatures of 20,30 and 40℃ was measured,and the experimental data were analyzed theoretically by Langmuir isotherm.The adsorptive isotherm of toluene was predicted by Polanyi theory,used the adsorptive isotherm of benzene,compared the results of mathematical computation and experiments data was consistent with the isotherm tested by experiments,and the maximum deviation was not more than 6% and 5.55%.
