Based on the biochemical theory of multiple ligand-receptor complexes (Klotz (1946)) a sigmoidal proceeding adsorption isotherm is derived. The special case of an arbitrarily large number of equal interaction sites and a separate one yields an equation which corresponds to the ζ-isotherm, disparately derived by Ward et al. (2007) for surface tension of solid-fluid interfaces. From the mathematical point of view it is analogous to the BET-isotherm for a limited number of adsorption layers (1938). It is shown that the isotherm maps type IV and V isotherms. The isotherm is compared with others including the type IV isotherm of Do and Do (2009). The present isotherm is unified in contrast to existing hybrid models. It is successfully applied to numerous literature data concerning the adsorption of water on microporous carbon and aluminophosphate molecular sieves.
基于多配体-受体复合物的生化理论（Klotz (1946)），推导出了一个呈 S 形的吸附等温线。对于任意数量的相等相互作用位点和一个单独的位点的特殊情况，得到了一个与 Ward 等人（2007）为固-液界面表面张力推导的 ζ-等温线不同的方程。从数学的角度来看，它类似于 BET 等温线（1938），用于有限数量的吸附层。结果表明，该等温线映射了 IV 型和 V 型等温线。该等温线与其他等温线，包括 Do 和 Do（2009）的 IV 型等温线进行了比较。与现有的混合模型相比，本等温线具有统一性。它成功地应用于许多关于水在微孔碳和磷酸铝分子筛上吸附的文献数据。
