摘　　要：采用二元溶液单分子层吸附方程计算苯胺、苯酚、环己醇、正丁醇、正己酸、正戊醇、正戊酸在6种炭吸附剂上的吸附等温线。42组数据计算值与实验值的均方差在0．0080．047之间，结果优于BET公式拟合结果。进一步计算骨炭从水溶液中吸附醋酸、硅胶吸附碱金属离子等吸附等温线，均获得良好结果。说明上述吸附质溶液在炭吸附剂上的吸附是单层吸附而非前人认为的多层吸附模式。According to statistical thermodynamics theory, We obtained an adsorption equation in bi- nary solution system at constant temperature condition. By means of computer and using abovemention e- quation, the adsorption data of aniline, phenol, cyclohexanol, 1-butanol, 1-pentanol, 1-pentanoic acid and 1-hexanoic acid on six carbon adsorbents have been calculated. It is expressing that the adsorption taken place in solution system is single layer adsorption not multi-layer adsorption .
