Notes:
The corrosion of Al in NaOH solutions has been investigated using polarization method as well as weight loss method. The effect of various organic and inorganic compounds on the rate of corrosion was studied. The results indicated that the rate of Al corrosion is maximum at [NaOH] ∼4M. Various benzoic acid as well as other organic acids inhibit the corrosion but to different extents depending on the structure. The inhibition is due to adsorption of these acids and not due to neutralizing effect. Some sulpher containing compounds inhibit the corrosion but to lesser extent than acids. Aniline and its derivative are mostly activators for corrosion.
