The article titled “A Study of N,N-Diethylammonium O,O′-Di(p-methoxyphenyl)dithiophosphate as New Corrosion Inhibitor for Carbon Steel in Hydrochloric Acid Solution” [1] contained an error in Section , Adsorption Isotherm. The text reading “In general, the values of around −20 kJ  or less negative are associated with an electrostatic interaction between charged inhibitor molecules and charged metal surface (physisorption) and those of −40 kJ  or more negative involve charge sharing or transfer of electrons from the inhibitor molecules to the metal surface to form a coordinate type bond (chemisorption). Based on (), the value of for EAPP on carbon steel in HCl solution at different temperatures is 33.11 kJ . It indicates that the adsorption of EAPP on carbon steel surface in 0.5 M HCl is chemical adsorption” should be updated as follows:

“Generally, it is usually accepted that the value of around −20 kJ  or less negative indicates that the adsorption is physisorption in which the inhibition action is due to the electrostatic interaction between the charged molecules and the charged metal [29–35]. On the other hand, the values which around −40 kJ  or more negative indicates that is corresponding to chemisorption process, which is attributed to the charge sharing or transfer processes from the inhibitor molecules to the metal surface in order to forming a sort of covalent or coordinate bonds [29–35]. The of EAPP on carbon steel in HCl solution is −33.11 kJ , which between −20 kJ  and −40 kJ , suggesting that the adsorption of EAPP molecules on carbon steel surface is not merely physisorption or chemisorption. It includes that a complex comprehensive kind of interaction, involving both physisorption and chemisorption (mixed adsorption), are taking place for carbon steel in HCl solution”.
