The Langmuir adsorption model explains adsorption by assuming an adsorbate behaves as an ideal gas at isothermal conditions. According to the model, adsorption and desorption are reversible processes.

2019年3月26日 · Despite its simplicity, the Langmuir adsorption model captures the key physics of molecular interactions at interfaces and laid the foundation for further progress in understanding interfacial phenomena, developing new adsorbent materials, and …

2020年11月1日 · The R–P model is an empirical hybrid model of the Langmuir and Freundlich models, which has been frequently applied in the homogeneous or heterogeneous adsorption processes. The R–P isotherm model can be described by Eq.

The Langmuir Isotherm describes the adsorption of a substance onto a solid surface. It defines the relationship between the concentration of an adsorbate (the substance being adsorbed) in solution and its coverage on the surface of an adsorbent (the solid material).

The Langmuir adsorption model is the simplest theoretical model for monolayer adsorption (Ruthven, 1938). It has been adopted to account for adsorption in gas shales and other engineering processes ( Tang et al., 2017 ; Fianu et al., 2019 ).

The 100th anniversary of Langmuir’s theory of adsorption is a significant landmark for the physical chemistry and chemical engineering communities. Despite its simplicity, the Langmuir adsorption model captures the key physics of molecular interactions at interfaces and laid the foundation for further progress in

Da̧browski studied the adsorption of direct dye onto a Novel Green Adsorbate developed from Uncaria Gambir extract; their equilibrium data were well described by the Langmuir isotherm model . 3.4. Freundlich Isotherm

The Langmuir adsorption model is most common for quantifying the amount of adsorbate adsorbed onto a material (called an adsorbent) as a function of partial pressure at a given temperature. It includes the following assumptions:

2021年5月26日 · Islam et al. (13) developed an adsorption kinetic model based on the Langmuir adsorption concept, in which for a given adsorption dosage, wa = W / V, three parameters, namely, maximum adsorption density (adsorption capacity) (q∞) and concentration-independent adsorption and desorption rate constants (ka and kd), completely described both adsorpt...

2024年5月20日 · Most texts describing Langmuir adsorption use a `kinetic model’, as indeed did Langmuir is his description of adsorption [1]. We consider the case where water is the solvent and substance j j is the adsorbate. In the absence of adsorbate j j, the surface of the adsorbent is covered with water.
