采用微波加热制备的秸秆活性炭作为吸附剂，研究了该活性炭对苯和甲苯的吸附性能。以苯在活性炭上的吸附等温线为依据，采用Dubinin-Radushkevich模型对实验数据进行拟合得出的参数，通过采用摩尔体积和摩尔电子极化度法计算亲和系数的基础上，再用Dubinin-Radushkevich模型预测了甲苯在微波秸秆活性炭上的吸附等温线。实验结果表明，预测值和实验值高度一致，其平均相对偏差仅为5.16%。因此，实验证明了Dubinin-Radushkevich模型可以用来预测具有微孔结构的秸秆活性炭吸附等温线，从而为更好的设计吸附工艺体系提供了重要了手段。

The adsorption properties of benzene and toluene in wheat straw activated carbon prepared by microwave heating was investigated. The adsorption isotherms of benzene was measured, and fitted by Dubinin–Radushkevich model. Based on the parameters obtained from benzene fitted isotherm model, the adsorptive isotherm of toluene was predicted by Dubinin–Radushkevich model, using molar volumes or electronic polarization. Compared the results of mathematical computation, experiments data was consistent with the isotherm tested by experiments, and the mean relative error is 5.16%. The Dubinin–Radushkevich equation was used to predict equilibrium adsorption capacity for hazardous organic vapors on two activat?ed carbons by the molar volume method.
