Comment on “Magnetic tubular nickel@silica-graphene nanocomposites with high preconcentration capacity for organothiophosphate pesticide removal in environmental water: Fabrication, magnetic solid-phase extraction, and trace detection” [J. Hazard. Mater. 457 (2023) 131788]

The field of adsorption is seen with mistrustfulness by Scientific Society. One of these reasons is that many users of adsorption do not have knowledge of several concepts of physical chemistry, and they spread misconceptions throughout the literature. One point that is usually found to be wrong in papers published even in prestigious Journals involving adsorption is the thermodynamics of adsorption, the use of linearization for modeling the equilibrium and kinetics of adsorption, and other misconceptions related to adsorption. In the paper, Journal of Hazardous Materials 457 (2023) 131788, some inconsistencies related to adsorption are seen, and this letter intends only to correct these small mistakes and not overrule the scientific content of this publication.
