Web1 mai 2015 · The Langmuir model assumes [54] that adsorption is monolayer adsorption on a uniform surface, and that the adsorption and desorption are in dynamic equilibrium. The Freundlich isotherm... WebThe adsorption was conformed to be the pseudo-second-order kinetic model and the Freundlich adsorption isotherm, namely, the dye adsorption of the aerogels was the multilayer adsorption on the uneven surface, and the mechanism of the adsorption was related to the π-π interaction. Web10 apr. 2024 · The Langmuir adsorption isotherm showed a linear correlation coefficient (R 2) equal to about 1 for all the dyes, indicating that the adsorption occurred as a monolayer. The adsorption kinetics followed the pseudo-second order model with a rate constant, ... and it specifies whether the process is monolayer or multilayer.
