Talinum triangulare leaf and Musa sapientum peel extracts as corrosion inhibitors on ZA-27 Alloy

With the current emergence of green chemistry to keep the environment safe, attention is being shifted towards using plant extracts as corrosion inhibitors. The inhibitive performances of Talinum triangulare leaf extract and Musa sapientum peel extract on the ZA-27 in 1.0 M and 1.5 M hydrochloric acid solutions were studied for 18 days using mass loss measurement. The corrosion inhibition efficiencies of the extracts were evaluated. The results showed promising anticorrosive performance in 1.0 M HCl. The average inhibition efficiencies recorded for Talinum triangulare leaf extract and Musa sapientum peel extract in 1.0 M HCl using 1% w/v of each extract after 18 days were evaluated as 62.30% and 63.27%, respectively, while in 1.5 M HCl; 40.54% and 38.45% were recorded for Talinum triangulare leaf extract and Musa sapientum peel as inhibitors, respectively, in 1.5 M HCl. *
