| Summary: | The present work investigate the inhibition of Jatropha Stem Extract (JSE) in
sea water using mild steel coupons of dimension 5 × 5 × 0.5 cm. The
cupons were immersed in test solutions of sea water and varied
concentrations of extracts of 0.1g/l to 0.9g/l was used. The functional
groups of the compounds was analyzed using an FTIR. The results showed
that as the concentration of the extract increases, there was a reduction in
the corrosion rates. Furthermore, as the extract concentrations increased
from 0.1g/l to 0.4g/l at 48hrs exposure time, the weight loss decreased by
14.3% in the medium. However, the Jatropha Stem Extract was absorbed on
the substrate surface to inhibit corrosion, the morphology of phases formed
from the scanning Electron Microscopy examination confirmed this trend.
Hence, JSE is a good and safe inhibitor in sea water solution. The FT-IR
results also indicates the presence of active corrosion inhibitor present in the
Jatropha Stem. |
