Soil sorption of caesium modelled by the Langmuir and Freundlich isotherm equations

, 1995
The Langmuir and Freundlich adsorption isotherm equations were used to model Cs sorption in 6 Welsh soils. The pH (in water), of the soils ranged from 3.5 to 6.5, and the estimated organic matter (determined by loss-on-ignition) ranged from 4.8% to 46 ...

Adsorption and desorption of gaseous sorbates on a bidispersed particle with Freundlich isotherm. I. Theoretical analysis

, 1989
A model for the sorption of gases onto a single sorbent particle is developed in this paper. Important features incorporated in the model are macropore and micropore diffusional resistances, non-linear (Freundlich) isotherm on the macropore surface ...

The Sips isotherm equation: Often used and sometimes misused

Separation Science and Technology, 2023
The Sips isotherm equation, proposed in 1948, is popularly used to describe the adsorption of a diverse array of water contaminants by engineered and natural adsorbents. However, that apparent popularity conceals problematic application issues.

Gibbsian interpretation of Langmuir, Freundlich and Temkin isotherms for adsorption in solution

Philosophical Magazine Letters, 2022
Adsorption is a physicochemical phenomenon important in both natural and engineering processes. In the research and practice of adsorption equilibrium, a long-standing challenge is how to reconcile the classical models proposed by Gibbs, Langmuir ...

Derivation of Pseudo-First-Order, Pseudo-Second-Order and Modified Pseudo-First-Order rate equations from Langmuir and Freundlich isotherms for adsorption

, 2020
The kinetics of adsorption for Langmuir and Freundlich isotherms has been explored theoretically on the basis of Statistical Rate Theory (SRT). The Modified Pseudo-First-Order (MPFO) and Pseudo-First-Order (PFO) models were derived from Freundlich ...

Study on the adsorption of dyestuffs with different properties by sludge-rice husk biochar: Adsorption capacity, isotherm, kinetic, thermodynamics and mechanism

Journal of Molecular Liquids, 2019
The adsorption capacity, isotherm, kinetics, thermodynamics and mechanism of four dyes with different properties on a novel economical sludge-rice husk biochar (SRHB) were determined.
