Abstract
In this study, water marjoram (Origanum marjorana L.) extract was evaluated as corrosion
inhibitor for zinc in 1.0 M HCl solution. The polarization measurements showed that this
inhibitor is acting as mixed inhibitors for both anodic and cathodic reactions. The results
showed that the inhibition efficiency was increased by increasing the inhibitor doses and
reached the maximum at 500 ppm. The adsorption of marjoram extract on zinc surface was
found to obey Langmuir type isotherm. The efficiency obtained from the impedance ...
