dc.description.abstractThe corrosion inhibition of mild steel by chitosan gel is investigated in peat water by using weight loss measurements. The results showed that the inhibition efficiency on static and dynamic system were 80.28% and 41.8% respectively. The spectrum analysis done by Fourier Transform Infrared Spectroscopy (FT-IR) from the corrosion product on steel surface showed that chitosan gel could obstruct the process of corrosion on mild steel in peat water media, because it formed Fe-chelating compounds. The characterization by Scanning Electron Microscopy (SEM) showed that chitosan gel forming a passivatable layer. To increase the corrosion inhibition efficiency in the dynamic system in this research done by modification with Cu2+ ions. The result of experiment showed that the increase of inhibition efficiency is reaching 60%.en_US
