Abstract
ABSTRACT The present study was aimed to investigate the Datura metel plant extract’s anti-corrosion ability on mild steel against sulphuric acid. A comprehensive set of experiments using conventional methodology were employed for asserting the efficacy and velocity of corrosion inhibitory performance. It was found that the effectiveness of inhibition was 85.73%. The results showed that potentiodynamic polarisation causes inhibition regulated anodic responses. Both factors, linear polarisation resistance and corrosion current were improved by the inhibitors. The protective layer on a vulnerable surface has been induced by the phenomenon known as the ‘blanket effect’. The observed outcome may be attributed to the constraints imposed by the experimental methodology. The protective layer composition of mild steel was analysed using FTIR spectroscopy. Additionally, SEM analysis revealed the protective layer was neither smooth nor rough. In summary, the extract derived from Datura metel could be a potential green inhibitor to act as an anti-corrosion agent.
