“…The Tafel slopes (b a and b c ) are approximately constant, indicating that the retardation of the two reactions (cathodic hydrogen reduction and anodic metal dissolution) were affected without changing the dissolution mechanism. [35][36][37] The degree of surface coverage (q) and the inhibition efficiency (h) were calculated using eqn (8):…”

The inhibition of corrosion of Sodium Dodecyl Sulphate and the synergistic effect with Zn 2+ taking place on the surface of carbon steel in well water medium were studied using mass reduction technique, cyclic voltammetry (CV), Atomic Force Microscopy (AFM), FTIR and Contact Angle measurement. The effects showed that there is a protective layer formed on the surface of carbon steel and also that the protective layer is stable even in presence of 3.5% sodium chloride solution. This confirms that there was a formation of self-assembled monolayer on the surface of the carbon steel and there was a synergistic effect occurs among Zn 2+ and Sodium Dodecyl Sulphate.

A new Azomethine derivative namely 5-(((4-hydroxybenzylidene)amino)methyl)quinolin-8-ol (HBHQ) was synthesized and identified by different spectroscopic methods. The product was assessed in the inhibition of corrosion of carbon steel (CS) in 1 M HCl using Tafel polarization, weight loss and electrochemical impedance spectroscopy. Their property anticorrosion is relative in concentrations and achieved 92% at the optimum concentration of 10-3 M. Polarization studies showed that that the newly synthesized inhibitor was of mixed type in nature. The EIS data bring that, the development of a protective layer of azomethine derivative increase the charge transfer resistance and decreases in the double layer capacitance of carbon steel in acid medium. The adsorption process at interface of carbon steel in hydrochloric acid by HBHQ was studied at different temperatures (298-338 K) by means of Tafel polarisation measurements. The adsorption of azomethine derivative on the carbon steel (CS) surface followed Langmuir adsorption isotherm and in order to discover the mode of adsorption process, various thermodynamic and activation parameters were evaluated. Quantum chemical calculations were performed using methods based on density functional theory (DFT/B3LYP) and Monte Carlo simulations (MCs). Indeed, the results obtained by this computation reflect a good agreement with the practical part.
