Comments on “Reasonable calculation of the thermodynamic parameters from adsorption equilibrium constant, Journal of Molecular Liquids 322 (2021) 114980.”

The determination of thermodynamics parameters of adsorption is a controversial issue in the adsorption field. The correct way of obtaining the adsorption thermodynamic parameters’ values involves obtaining adsorption isotherms at least four different temperatures. However, this correct procedure demands much experimental work, and some researcher wants to take a shortcut to obtain faster results, independently if these results have or not physical meaning. However, in the paper Journal of Molecular Liquids 322 (2021) 114980, the authors want to turn official the incorrect way of obtaining confident results of thermodynamic parameters. Practically, every definition written in the paper is biased, with several not funded definitions that would lead to the Adsorption Field's trivialization. This comment will correct the misinformation published to avoid the propagation of error throughout the literature.
