Abstract :
The effect of podophyllum hexandrum fruit extract as an inhibitor for mild steel in 1N HCl using weight loss method has been investigated. The corrosion coupons were immersed in 1N HCl solution containing varying inhibitor concentrations (1%, 2%, 3%, 4% and 5% v/v) within a period of 1–4 hours. From the result, it was found that the adsorption of podophyllum hexandrum fruit extract reduced the corrosion rate in acid medium. The inhibitive action of this plant extract has been found to be significant. The most suitable inhibitor concentration was found to be 5% for an inhibition efficiency of 89%. The inhibition is attributed to physical adsorption. The adsorbed molecules of the inhibitor lie on the surface of the mild steel blocking the active corrosion sites on the alloy. This makes the alloy to have a higher corrosion resistance in the studied environment.
