测定了轻质正构烷烃在三种不同的活性碳上的吸附等温线，并与苯在这些炭上的吸附等温线进行了比较。通过Dubinin-Radushkevich方程的分析表明，乙烷、丙烷和正丁烷的吸附等温线可用于描述活性炭微孔结构。在这些研究的基础上，作者建议使用正丁烷作为微孔活性碳表征的参比吸附剂。
Adsorption isotherms of light normal alkanes on three different activated carbons were measured and compared with benzene adsorption isotherms on these carbons. Analysis by means of the Dubinin-Radushkevich equation revealed the utility of the adsorption isotherms of ethane, propane, and n-butane for describing the microporosity of activated carbons. On the basis of these studies, the authors recommend that n-butane be used as a reference adsorbate for characterization of microporous activated carbons.
