Abstract

Surface coverage and corrosion rate of taro tuber methanol extract on mild steel in dilute 0.5 M sulfuric acid solution were studied through a weight-loss method, FT-IR spectroscopy, and SEM. The result obtained in 0.5 M sulfuric acid solution for 72 hours with optimal surface coverage was 0.86. The corrosion rate was found to be decreased and surface coverage was increased with the increasing concentration of taro tuber methanol extract which was added. The results showed that taro tuber methanol extract was a good corrosion inhibitor.
