Hyssopus Officinalis

The influence of Hyssopus officinalis (L), (Hyssop), or (Zoufa) on the corrosion of mild steel and zinc alloy in 0.5 M HCl solution was tested through open circuit potential-time measurements (OCP), potentiodynamic polarization, as well as electrochemical impedance spectroscopy (EIS) techniques. Hyssop leaf extract exhibited good inhibition efficiency in HCl solutions for both metals. To determine the nature of interaction among the leaf extract and both metallic surfaces, the experimental data have been tested with several adsorption isotherms. The thermodynamic activation parameters were calculated. The data showed that the adsorption process on both metals occurs through a physical adsorption mechanism. Hyssopus officinalis (L) leaf extract can be suggested as an effective green inhibitor of corrosion of mild steel and zinc alloy in HCl solutions.
