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 ...

Application of isotherms models and error functions in activated carbon CO2 sorption processes
Microporous and Mesoporous Materials, 2023 This work is concerned with the calculations using eight different isotherm models (Langmuir, Freundlich, Halsey, Temkin, Toth, Sips, Radke-Prausnitz, and Redlich-Peterson) to fit the experimental isotherm data of CO 2 on activated carbon (AC). Moreover,

Determination of biosorption mechanism in biomass of agave, using spectroscopic and microscopic techniques for the purification of contaminated water [PDF]
, 2019 [Abstract] Lead (Pb2+) and copper (Cu2+) are polluting metals due to their toxicity; however, the extraction of these metals is essential for economic development, so it is important to look for efficient and low-cost alternatives that can remove heavy ...
