Green Corrosion Inhibitor by Ethanolic Extract of Lantana camara for corrosion of aluminium in acidic media
Keywords:Corrosion inhibition, Aluminium, Adsorption, Lanatana camara
The corrosion inhibition of aluminium in sulphuric acid solution in the presence of different plant parts viz. leaves, stem bark and fruit was studied using weight loss method and thermometric method. The ethanolic extracts of Lanatana camara were found to inhibit corrosion. The inhibition efficiency was found to increase with the increase in inhibitor concentration. The inhibition was attributed to the adsorption of the plant part on the surface of aluminium metal. The green corrosion inhibitors are cheap, easily available and biodegradable.
