Langmuir Adsorption Kinetics in Liquid Media: Interface Reaction Model [PDF]
ACS Omega, 2021 Adsorption kinetic equation has been derived assuming that the process follows the behavior of a heterogeneous chemical reaction at the solid-liquid interface. This equation is converted into the Langmuir isotherm at equilibrium and describes well the unsteady-state adsorption process.

Revised Disrupted Langmuir–Adsorption Model of Photocatalysis [PDF]
The Journal of Physical Chemistry C, 2015 The increasingly popular disrupted Langmuir–adsorption (DLA) kinetic model of photocatalysis does not contain an explicit function for the dependence of rate on the irradiance, ρ, but instead has a term αρθ, where, α is a constant of the system, and θ is also a constant equal to 1 or 0.5 at low or high ρ values, respectively.

Modelling focused electron beam induced deposition beyond Langmuir adsorption [PDF]
Beilstein Journal of Nanotechnology, 2017 In this work, the continuum model for focused electron beam induced deposition (FEBID) is generalized to account for multilayer adsorption processes. Two types of adsorption energies, describing both physisorption and spontaneous chemisorption, are included.

Adsorption and removal of direct red 31 by Cu-MOF: optimization by response surface
Water Science and Technology, 2022 Cu(PABA) is a Cu-based MOF material assembled from Cu2+ and the organic ligand p-aminobenzoic acid (PABA). Cu (PABA) was synthesized by a solvothermal method, characterized and applied to the adsorption of direct red 31 dye (DR-31). The effects of pH, DR-

A Prediction Model for Methane Adsorption Capacity in Shale Gas Reservoirs
Energies, 2019 Estimation of methane adsorption capacity is crucial for the characterization of shale gas reservoirs. The methane adsorption capacity in shales is measured using high-pressure methane adsorption to obtain the adsorption isotherms, which can be fitted by
