Exploiting the Extract Constituents of Pentaclethra Macrophylla Bentham (Ugba) Leaves in the Corrosion Inhibition of Mild Steel in Acidic Media
Journal Title: International Journal of Engineering and Science Invention - Year 2019, Vol 8, Issue 1
Abstract
The chemical constituents of Pentaclethramacrophylla (PM) were investigated by phytochemical, GC-MS and FTIR analysis and exploited in the corrosion inhibition of mild steel in acidic media. The phytochemical results revealed the presence of saponin, alkaloid, flavonoid, tannin and phenol which shows that PM extract is a prospective corrosion inhibitor. Also the GC-MS and FTIR results showed that the extract contained some functional groups that are expected to aid corrosion inhibition. Weight loss and electrochemical results indicated that PM extract functioned as a good corrosion inhibitor for mild steel via the adsorption of its extract constituents on the mild steel surface which was confirmed by the scanning electron microscopy results.
