Abstract
Efficiency of acid extracts of dry leaves of Millingtonia Hortensis(MH) as corrosion inhibitor for mild steel in H2SO4 medium is investigated in the present study by weight loss method and FT-IR Spectroscopy. The results indicate MH leaves to be good inhibitor having efficiency as high as 98.99% at 2% inhibitor concentration. Inhibitor efficiency increases with concentration of the extract. Temperature studiesshow that inhibition efficiency decreases with increase in temperature. Adsorption isotherms reveal that it obeys Langmuir isotherm.
