Langmuirisotermen
Langmuirisotermen is a term used in adsorption science to denote the Langmuir isotherm family, named after Irving Langmuir. These models describe how a sorbate distributes between a bulk phase and a solid surface at equilibrium, under the assumption that adsorption occurs on a finite number of identical, independent sites and forms a single molecular layer. They are widely applied to gas and solution-phase systems to estimate surface properties from adsorption data.
The core relation of Langmuirisotermen expresses the amount adsorbed q as a function of pressure or concentration.
Assumptions underlying Langmuirisotermen include a homogeneous surface with equivalent adsorption sites, no interaction between adsorbed molecules,
Applications span surface science and chemical engineering, including estimation of surface area, catalyst characterization, and modeling
