The Langmuir model was originally proposed to describe adsorption of gas molecules onto homogeneous solid surfaces (crystalline materials) that exhibit one type of adsorption site as in Langmuir ( 1918 ).
WebSep 14, 2024 · Freundlich vs. Langmuir Adsorption Isotherms Concepts Berg What is the difference between Freundlich’s and Langmuir’s adsorption isotherms? When the amount of adsorbate adsorbed is plotted against changing pressure, Freundlich adsorption isotherms give a straight line with a slight curvature at higher pressure. WebLangmuir model is associated with monolayer adsorption, while Freundlich one is related to multilayer adsorption. I have seen in some papers that, according with the previous info, Langmuir...
