“…45 Here, we plotted logð 22,23,46 Here, the adsorption of BTAOH on the mild steel surface in 1 mol/L HCl is a exothermic process, which validated the conclusion in the sections of ÁG 0 ads and E a calculation that BTAOH is physisorption on the mild steel surface in the 1 mol/L HCl. The very little negative ÁS 0 ads reveals that, the increase of disorders due to desorption of more water molecules from the mild steel surface almost equals to the decreases of one BTAOH physical confined on the mild steel surface and in the zig-zag polymer structure.…”

The inhibition ability of 1-hydroxy benzotriazole (BTAOH) for mild steel in HCL solution (1 mol/L) had been investigated in this manuscript. The inhibition efficiency of BTAOH showed a maximum value around 48% at 303 K, with the concentration 1.5 × 10 −3 mol/L. The physical adsrobed BTAOH molecules are more stable attached onto the mild steel surface than the corrosion products. The similar free energy of adsorption (ΔG 0 ads ) but much lower IE were ascribed to the thicker but less compact film constructed by the zig-zag H-bond connected BTAOH polymers. According to the effects of concentration and temperature on the adsorption behavior of the BTAOH, we had calculated the ΔG

The inhibition effect of 2,2'-(((thiobis (4,1 phenylene)) bis(azanylylidene)) bis(methanylyidene)) bis(4-methoxyphenol) (BIS-IMIN) on the corrosion behavior of 304-stainless steel (SS) in 0.5 M HCl solution was studied by electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization techniques. SEM, FT-IR, 1 H-NMR, 13C-NMR methods used for characterization of BIS-IMIN. Potentiodynamic polarization curves indicated that BIS-IMIN act as mixed type inhibitor. The adsorption of the inhibitor was more suited with the Langmuir adsorption isotherm and kinetic parameters K ads , ∆G ads, E a , ∆H ads, ∆S ads were determined at room temperature. The results showed that BIS-IMIN performed well inhibiting effect for the corrosion of the SS.

“…The solubility of aluminum oxide film formed on its surface increases beyond the limits of a pH range from 4 to 9 1 . The inhibition of materials corrosion by non-toxic organic inhibitors and heavy metal free is an encouraging solution that can effectively replace the use of chemical inhibitors [2][3][4] . The mechanism action of organic inhibitors is explained by physical and / or chemical adsorption on the metal surface 3,[5][6][7] .…”

“…The inhibition of materials corrosion by non-toxic organic inhibitors and heavy metal free is an encouraging solution that can effectively replace the use of chemical inhibitors [2][3][4] . The mechanism action of organic inhibitors is explained by physical and / or chemical adsorption on the metal surface 3,[5][6][7] . This inhibitive action depends on the physicochemical properties of the inhibitor atoms such as the functional group and the aromaticity as well as the presence of the heteroatoms [8][9][10] , without forgetting the nature of the surface, the temperature and the pressure of the reaction 11 .…”

The study was carried out using potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) technique. The inhibition efficiency was found around 87 % with 1600 ppm of inhibitor. The efficiency was accentuated with the increase of the concentration while it decreased with the rise of the temperature. Analysis of the polarization curves revealed that the Ricinus communis oil is considered as a mixed inhibitor. The Influence of the temperature was also studied, the values of the activation energy showed that the inhibition occurred by physisorption.
