Abstract: | The alkaloid content of the leaves and stem bark of Xylopia ferruginea plant was isolated and tested for its anticorrosion potential on mild steel corrosion in a hydrochloric acid medium by using
electrochemical impedance spectroscopy, potentiodynamic polarization measurement, scanning electron microscopy (SEM), and
Fourier transform infra red (FTIR) analysis. The experimental results reveal the effective anticorrosion potential of the
plant extract. The mixed mode of action exhibited by the plant extract is evidenced from the polarization study. SEM images
proof the formation of a protective layer over the mild steel surface, and this is supported by the FTIR study. The possible
mode of the corrosion inhibition mechanism has also been discussed. |
