Corrosion Inhibitive Potential Of Hibiscus Sabdariffa Calyx Extract For Low Carbon Steel In 0.5M H2SO4 Acid Solution
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 3, Issue 8
Abstract
The inhibitive potential of Hibiscus Sabdariffa calyx extract on low carbon steel corrosion in 0.5M H2SO4 have been investigated by weight loss method which is considered more informative than other laboratory methods. The studies were carried out using extracts obtained from 5-25g dried calyx powder. The test coupons were immersed in the corroding media at the time intervals of 24-168hours. The results obtained showed that the concentration of the inhibitor in the corrodent impacted differently on the test coupons. The corrosion rate was found to decrease while inhibition efficiency increase as the concentration of the extract was increased. The maximum inhibition efficiencies of 95.01% and 94.41% were obtained at 96hours exposure time from the extract of 20g and 25g dried calyx powder respectively.The results has clearly shown that the extract has the inhibiting capacity for reducing the corrosion of low carbon steel in the acidic medium.
