Corrosion inhibition of mild steel by Capsicum annuum fruit paste

Publication date: Available online 5 July 2016 Source:Perspectives in Science Author(s): Chandan M. Reddy, Bhargav D. Sanketi, S. Narendra Kumar The anti-corrosive property of Capsicum annuum fruit paste (CFP) on mild steel was investigated. Weight loss and SEM analysis showed that the aqueous and ethanolic solutions of CFP exhibits excellent corrosion inhibition in 2M HCl. Contact angle, surface atomic composition and FTIR studies verified the presence of an organic film on the mild steel surface. The FTIR spectra also indicated the formation of active compound- Fe complex. CFP thus shows potential as an inexpensive environment friendly corrosion inhibitor for mild steel.
