Abstract : - This work studies the use of Eupatorium odoratum (E.O) as corrosion inhibitor of mild steel in 1.0M H2SO4 acid. The effects of temperatures on the inhibition efficiency of Eupatorium odoratum were also tested at temperature of 300C and 600C respectively. The weight losses of the mild steel were taken for complete four days, for the two temperatures. The rates of corrosion of the mild steels were found to increase with increase in concentration of the acid and also decreases with increase in concentration of the Eupatorium odoratum.. The Eupatorium odoratum gave an inhibition efficiency of 71% at the concentration of 0.5g/l, which shows that it is a good corrosion inhibitor of mild steel in acidic medium. This efficiency was found to decrease as the temperature increases and also the activation energy value calculated showed that the Eupatorium odoratum is physically adsorbed on the mild steel coupons.
