“…Some literature on the usage of carboxamide derivatives as corrosion inhibitors is available. For example, Dadgarinezhad and Daghael [20] explored the corrosion inhibition potential of 2-phenyl-1-hydrazine carboxamide in H3PO4, and observed that the adsorption mechanism obeyed the Langmuir's isotherm. Chafig et al [21] reported (E)-2-(4-(2-(methyl(pyridine-2yl)amino)ethoxy) benzylidiene)hydrazine-1-carboxamide as a cost-effective and efficient corrosion inhibitor, with maximum IE (%) of 97%, at a C of 0.005 M. Their experimental findings were in good agreement with data generated from theoretical calculations.…”

Two novel synthesized compounds (FD and ACP) have been applied as inhibitors for MS corrosion in HCl and H2SO4 solutions. Gravimetric, PDP, EIS, SEM and theoretical approaches were employed for the investigation of FD and ACP synthesized compounds IE%. Their corrosion IE% and calculated quantum chemical properties were comparable to each other, and indicated that ACP is a slightly less effective inhibitor than FD in HCl and H2SO4 solutions. Langmuir's, Temkin's, Frumkin's and Freundlich's adsorption isotherms were used for describing the inhibitors adsorption behavior. The adsorption was spontaneous and followed a mixed mechanism, but with initial physisorption. Polarization data revealed that the inhibitors were more cathodic, because they tended to enforce MS HER retardation. The inhibitors decreased the electrolyte impedance, while Rct increased. The adsorption mechanism was influenced by the protonation and solvation environment, and it was concentrated within the heteroatoms and the aromatic systems. Calculated quantum parameters agreed effectively with the obtained experimental results, while FF indices were useful for predicting the nucleophilic and electrophilic attacks positions.

“…It is generally agreed that corrosion inhibition is due to the adsorption of the inhibitor molecule at the metal-solution interface [23]. Adsorption isotherm importance is related to its information about the interaction between molecules and metal surface [24].…”

Adsorption isotherm of N,N′-bis(2,4,6-trihydroxyacetophenone)-2,2-dimethylpropandiimine (THAPDP) as an environmentally friendly Salen Ligand corrosion inhibitor on mild steel was studied in alkaline solution (pH=10) containing 3% NaCl. Measurements were carried out using electrochemical and surface techniques. Potentiodynamic polarization curves suggested that this compound was an effective corrosion inhibitor for mild steel and the protection efficiency was increased with the increase in inhibitor concentration. The experimental results indicated that this organic compound was a mixed-type inhibitor. Adsorption on the mild steel surface followed the Langmuir isotherm model. Activation parameters and thermodynamic adsorption parameters of the corrosion process such as E a , ΔH, ΔS, K ads , and ΔG ads were calculated at different temperatures.
