摘　　要：对已有的表面活性剂液固界面吸附等温线进行了系统的分类，并提出了非均匀表面两阶段吸附模型．用此模型导出的吸附等温方程式能很好地描述各种类型的吸附等温线.In this paper,the adsorption isotherms of surfactants on liquid--solid interface have been classified systematically,and a nonuniform surface two step adsorption model has been developed by the authors.By using the adsorption isotherm equations derived from this model,the correlation of experimental isotherms of L-shape,S-shape,LS-shape,and special shape with maximum and minimum are realized.The agreement between calculated results and experimental data is good.
