| The corrosion inhibition of mild steel in HCl solution in the presence of Ipomoea batatas peel extract (IBPE) at a temperature range of 30°C to 60°C was studied using the chemical weight loss method. The IBPE acts as an inhibitor in the acid environment. The inhibition efficiency (IE) increases with increase in inhibitor concentration but decreases with an increase in temperature and concentration of acid. 93.96%, 89.99% and 85.61% IE were obtained at 6.67 g/L extract in 0.5, 1.5 and 2.5M acid media respectively at temperature of 30°C. 84.86%, 83.99% and 81.13% IE were obtained at 6.67 g/L extract in 0.5, 1.5 and 2.5M acid media respectively at temperature of 40°C. Also 78.92%, 76.21% and 75.73% IE were obtained at 6.67 g/L extract in 0.5, 1.5 and 2.5M acid media respectively at temperature of 50°C, while 71.45%, 69.87% and 66.00% IE were obtained at 6.67g/L extract in 0.5, 1.5 and 2.5M acid media respectively at temperature of 60°C. The inhibitive effect of the IBPE could be attributed to the presence of some compound in the peel which is adsorbed on the surface of the mild steel. The peel extract was found to conform to the Langmuir adsorption isotherm and Freundlich adsorption isotherm at all the concentration levels and temperature studied |
