The corrosion inhibition efficiency of a potential polynuclear Schiff base, (s)-2-(anthracene-9 (10H)-ylidene amino)-5-guanidinopentanoic acid (A9Y5GPA), on carbon steel (CS) in 1 M hydrochloric acid solution has been investigated using weight loss measurements, electrochemical impedance spectroscopy (EIS), and potentiodynamic polarization studies. The corrosion inhibition efficiencies of parent amine [(s)-2-amino-5-guanidinopentanoic acid] and parent ketone (anthracene-9 (10H)-one) on carbon steel in 1.0 M hydrochloric acid solution have also been investigated using weight loss studies. The electrochemical and weight loss data established that the inhibition efficiency on CS increases with the increase in the concentration of inhibitor, A9Y5GPA. The adsorption of A9Y5GPA obeys the Langmuir adsorption isotherm. Thermodynamic parameters (Kads, ΔGads0) were calculated using the adsorption isotherm. Activation parameters of the corrosion process (Ea, ΔH* and ΔS*) were also calculated from the corrosion rates obtained from temperature studies. Tafel plot analysis revealed that A9Y5GPA acts as a mixed-type inhibitor. A probable inhibition mechanism was also proposed. Surface morphology of the carbon steel specimens in the presence and absence of the inhibitor was evaluated by SEM analysis.

The corrosion inhibition of S-benzyl o-phenylenedioxydithiophosphate (BPOTP), for carbon steel in hydrochloric acid solution was studied by electrochemical measurements and weight loss measurements. Polarization curves indicate BPOTP is a mixed-type inhibitor, and the effects of temperature, hydrochloric acid concentration and immersion time were also studied. The studies of weight loss measurement show that the inhibition efficiency was up to 92.82 % at the BPOTP concentration of 40 mg·L-1 in 1.0 M hydrochloric acid solution at 30°C. The adsorption of BPOTP on carbon steel surface obeys the Langmuir isotherm.

The corrosion inhibition effect of some anionic surfactants (Diisononyl phthalate (A), N-oleyl-1, 3-propane –diamine (B), and Sodium lauryl sulphate (C)) on the corrosion of carbon steel in 1M hydrochloric acid solution were studied by chemical method (weight loss) and electrochemical methods (potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). From the results, it was clear that these surfactants are good inhibitors for corrosion of carbon steel in 1M HCl solution. Their inhibition depends mainly on their concentrations and temperature of solution. Polarization data revealed that these surfactants act as mixed type inhibitors. The surfactants adsorptions were found to follow Langmuir’s adsorption isotherm. The thermodynamic parameters of activation and adsorption were calculated and discussed. Adsorption of used surfactants led to a reduction in the double layer capacitance (Cdl) and an increase in the charge transfer resistance (Rct). All measurements used confirmed the adsorption of the surfactants used on carbon steel surface. Confirmation of these various independent techniques proved validity of the obtained data.
