Freundlich isotherm history
WebThe results showed that the pseudo-second-order adsorption kinetic was predominated for the adsorption of CV onto nanocomposites. The experimental equilibrated adsorption capacity of nanocomposites was analyzed using Freundlich and Langmuir isotherm models. The results corroborated that the experimental data fit the Freundlich isotherm …

WebFreundlich Isotherm. The Freundlich isotherm, presented by Freundlich in 1906 (Gaballah et al., 1997), was the first isotherm model proposed for sorption processes. It can be applied for nonideal sorption on heterogeneous surfaces, as well as, multilayer sorption. The extent of adsorption from solution is related to concentration by an ...
WebApr 10, 2024 · Adsorption isotherms obtained through volumetric measurements are widely used to estimate the gas adsorption performance of porous materials.
