测定了298 K下正己烷/正辛烷、正辛烷/正十四烷和正己烷/正十四烷二元混合物在TA 95活性炭上的吸附等温线，并用数学函数进行了描述。用气相色谱法测定了298 K时正己烷/正辛烷/正十四烷三元混合物在TA 95活性炭上的吸附过量值。借助坐标变换和利用摩尔分数的准双组分表示的概念，在三维空间中表示三元数据。从二进制数据计算的比湿吉布斯能的一致性测试进行。证明了从二元混合物的吸附数据的三元数据的数学预测的可能性。版权所有1999年学术出版社。
The adsorption isotherms of the binary n-alkane mixtures n-hexane/n-octane, n-octane/n-tetradecane, and n-hexane/n-tetradecane on the activated carbon TA 95 are measured at 298 K and described with mathematical functions. About 40 experimental values of the adsorption excess of the ternary mixture n-hexane/n-octane/n-tetradecane on activated carbon TA 95 at 298 K are gas chromatographically measured inside the ternary triangle. The ternary data are represented in the three-dimensional space with the help of transformation of coordinates and by utilization of the conception of the quasi-two-component representation of the mole fractions. A consistency test for the specific wetting Gibbs energies calculated from the binary data is carried out. The possibilities for a mathematical prediction of ternary data from adsorption data for the constituent binary mixtures are proved. Copyright 1999 Academic Press.
