Synergistic Effect between Natural Honey and 0.1 M KI as Green Corrosion Inhibitor for Steel in Acid Medium

The inhibition process of steel against corrosion in 1.0 M HCl using natural honey in the presence and absence of 0.1 M KI was studied at 25–55 °C utilizing a potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) measurements and gravimetric method. Corresponding surfaces of ste...

Summary:The inhibition process of steel against corrosion in 1.0 M HCl using natural honey in the presence and absence of 0.1 M KI was studied at 25–55 °C utilizing a potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) measurements and gravimetric method. Corresponding surfaces of steel were examined by SEM and EDX techniques. The obtained data demonstrated that inhibition efficiency increased by increasing both natural honey dose and environment temperature. Synergism parameter values were found more than one indicating that the inhibition efficiency of natural honey enhanced by an addition of KI due to synergism. The adsorption of natural honey in the presence and absence of iodide ions on the steel surface was found to follow Langmuir adsorption isotherm.
