Abstract

The inhibitive effect of the extract of Salvia Judica on aluminum corrosion in 1 M NaOH solutions was investigated by using the weight loss method at different temperatures. It was found that the extract play as corrosion inhibitor for aluminum corrosion in 1 M NaOH solution. The inhibition action of the extract was discussed in view of Langmuir and Temkin adsorption isotherms. It was found that the adsorption of the extract on aluminum surface is a spontaneous process. The inhibition efficiency was found to increase with increasing concentration of the extract and decreased with increasing temperature.
