In this study, the inhibitive properties of Myrtus Communis in sulfuric acid solution on the copper surface were examined by weight loss, potentiodynamic polarization, electrochemical impedance spectroscopy, atomic force microscopy, and scanning electron microscopy methods. Weight loss and electrochemical analysis showed that the Myrtus Communis extract was a highly efficient mixed type inhibitor. Also, it was found that the adsorption of Myrtus extract on the copper surface followed Langmuir adsorption isotherm. The inhibition efficiency was found to be increased with increasing immersion time of samples in the solution. Surface analysis attested to the inhibition action of Myrtus Communis extract as well.
