The simplest and direct way to apply green chemistry in corrosion protection, is to utilize eco-friendly, non-hazardous, reproducible and efficient green corrosion inhibitors (extracts of plant materials). The corrosion inhibition efficacy of alcoholic extract of different aerial parts of plant Tribulus terrestris for aluminium in acid media has been studied in relation to the concentration of inhibitor by mass loss method. It has been observed that the Tribulus terrestris alcoholic extract acts as a good corrosion inhibitor in acidic solution and the adsorption of the extract provides a good protection against aluminium corrosion. It has been observed that the inhibition efficiency increases with inhibitor concentration. The negative sign of the free energy of adsorption indicates that the adsorption of the inhibitors on the aluminium surface was a spontaneous process and was found to be physisorption. Adsorption process follows Langmuir adsorption isotherm.
