Langmuir theory

Yang Cite this: … WebbLangmuir (1918) was the first to propose a coherent theory of adsorption onto a flat surface based on a kinetic viewpoint, that is there is a continual process of bombardment of molecules onto the surface and a corresponding evaporation (desorption) of molecules from the surface to maintain zero rate of accumulation at the surface at equilibrium.

WebbLangmuir refinou e desenvolveu as idéias de Lewis, criando sua própria teoria atômica. Na teoria de Langmuir, que podia ser aplicada também aos átomos mais pesados e explicava a estabilidade dos gases nobres, os elétrons estavam arranjados em camadas concêntricas em torno do núcleo.
Webbtheories linked to the adsorption equilibrium. In the present study, the Langmuir, Freundlich and Dubinin-Radushkevich (D-R) isotherm models are employed and their expressions are given by Equations (9), (10) and (11), respectively [13,14,15]. The Langmuir theory assumes that adsorption takes place at Webb- Langmuir theory also suggests that the molecules do not interact with one another. However, this is incorrect as there are always weak forces of attraction that exist …
