非均匀表面两阶段吸附模型的改进

Modified Uniform Surface Two - Step Adsorption Model

非均匀表面两阶段吸附模型是适用于各种类型吸附等温线的表面活性剂固液界面吸附热力学模型。为了更好地反映第3组分(助剂、第二表面活性剂、无机盐和碱等)对表面活性剂吸附的影响,本文对非均匀表面两阶段吸附模型进行改进,导出了新的能用于有极限吸附和无极限吸附体系的吸附等温方程式。用此方程式关联合第3组分体系的吸附实验结果,计算值和实验值符合很好。

A modified uniform surface two-step adsorption model has been developed. By using this model, the new adsorption isotherm equation was deduced and the correlation of the isotherms of the surfactant on the solid/liquid interface with third component was realized. The agreement between calculated values and experimental data is good.
