In an adsorption experiment, I will utilize the Langmuir isotherm model and the Freundlich isotherm model in my research. In my study article, I'd want to make a few explanation about the application of these models

Isotherm modeling helps to understand the mechanism of sorption. Kn idotherm duties we check to which model does our date fit. Langmuir model suggests monolayer binding while Freundlich model suggests that binding between sorbent and sorbate is in multilayer. There are lot of isotherm models- each with different assumptions. Fitting data to a model suggests that the assumptions if that model ard true gor our data.
Limenew Abate, The possibility of drawing conclusions based on the fit of various isotherms to the equilibrium data is limited. In the case of the Langmuir isotherm, a conclusion can be drawn about a potential monolayer adsorption, but it is better to confirm it with physicochemical tests of the adsorbent surface. The value of qm can also be determined. In the case of the Freundlich isotherm, which is actually an empirical power function, no reliable conclusions are possible for liquid-solid adsorption. However, it can be used for local approximation of the equilibrium data.
Maybe you could share your data. Then it's easier to advise something.
