Abstract
Rosemary oil was investigated on carbon steel in 0.5M sulphuric acid through weight loss technique. It was observed that weight loss, inhibitor efficiency and corrosion rate differ in concentration of the oil and exposure time. Maximum inhibitor efficiency of 78.45% was obtained at 10ml concentration of the oil. The performance of the oil was associated with the existence of organic compounds such as alkaloids, flavonoids, tannins, among others which form a protective film and act as a barrier against corrosion attack in sulphuric acid environment.
