Abstract
The protection efficiency of seed coat of Coffea Arabica
fruit extract on the corrosion of mild steel in 1 M HCI and
0.5 M H2SO4 were evaluated by using Gravimetric method.
The study was carried out by varying the parameters like
inhibitor concentration, immersion period and temperature.
The maximum efficiency was obtained at 2.5 %(v/v)
concentration of the inhibitor in both 1 M HCI and 0.5 M
HzS04. The protective action of the acid extract was
maximum at 12 h in both 1M HCI and 0.5 M H2SO4. In the
temperature study the maximum efficiency was obtained at
333 K in 1M HCI and at 323 K in 0.5 M H2SO4.
