测定了丙酮－正己烷、甲苯－正己烷、苯－正己烷、正戊烷－正己烷四个二组分气体在部分石墨化的灯黑上的吸附等温线，并测定了单组分气体吸附等温线．对比了上述四个二组分气体，分别在硅胶、硅烷化硅胶和灯黑上吸附的十二个吸附体系的吸附规律．结果表明，二组分气体在吸附剂上的竞争吸附的强弱，基本上可以通过它们的纯组分气体在吸附剂上第一层吸附热Q1数值的大小加以预测． The adsorption isotherms of acetone-n-hexane, toluene-n-hexane, benzene-n-hexane and n-pentane-n-hexane on partially graphitized lampblack were measured. Isotherm. The adsorption behavior of twelve adsorbents adsorbed on the silica gel, silanated silica gel and lamp black respectively was compared with the above four two-component gases. The results show that the competitive adsorption of the two component gases on the adsorbent can be predicted by the magnitude of the adsorption heat Q1 of the first component of the pure component gas on the adsorbent.
