Comments on “removal of methylene blue dye from aqueous solution using citric acid modified apricot stone”
Jean‐Claude Bollinger, Hai Nguyen Tran, Éder C. Lima
Abstract
The work mentioned in the title of this comments-typed paper contains several calculations that disagree with some basic chemistry concepts. These misleading calculations mainly include (i) both kinetic and isotherm modeling through linear equations and (ii) calculating the thermodynamic parameters for the adsorption processes. Thus, we remind how to correct ways allowing to make these calculations. In our opinion, it is a source of confusion for the scientific community to continue using inappropriate methods as applied in the original paper.
