二元液体混合物非理想吸附平衡数据的预测

PREDICTION OF ADSORPTION EQUILIBRIA FOR NONIDEAL ADSORBED SOLUTION OF BINARY LIQUID MIXTURES

根据气相吸附和液相吸附的热力学一致性条件 ,从溶液理论、表面热力学出发并结合相交换模型 ,提出从气相吸附平衡数据预测二元液体混合物吸附平衡的模型 ,模型中仅含 4个未知参数 .应用该模型对二元液体吸附体系进行了预测 。

Using the thermodynamic consistency of adsorption for vapor or liquid phase together with the consideration of solution theory,surface thermodynamics and phase exchange model, the model for prediction of adsorption equilibria from binary solutions on solids with the adsorption isotherm of pure unsaturated vapors was proposed.The model only has four unknown parameters.Binary systems were tested with the proposed method.The results show that the predictive values have a good quantitative agreement with the experimental data.
