Study Of Corrosion Inhibition Effect Of Punica – granatum Fruit – Shell Extract On Carbon Steel In 0.5M Hydrochloric Acid Solution

Abstract

Naturally occurring substances are increasingly being tried as corrosion inhibitors of metals in acid cleaning processes to replace some toxic and expensive chemicals currently in use. The inhibitive action of Punica – granatum fruit – shell extract was investigating in 0.5M Hydrochloric acid by weight loss measurements. The work showed that the additive retarded the dissolution of carbon steel to an extent depending on the concentration of the additive. The surface coverage (?) data augment the above observation and the inhibition is attributed to the physical adsorption of the chemical components of the additive on the surface of the carbon steel. Inexpensive environmentally safe inhibitor formulations indicate have been obtained.
