Resumo: The influence of 3-hydroxy-2-methylquinazoline -4-one on the corrosion inhibition of mild steel in 1 M HCl and 1 M H2SO4 has been studied using weight loss, and galvanostatic polarization studies. Result obtained reveals that this organic compound is a very good inhibitor and its inhibition efficiency increases with increasing its concentration to attain 92% at 1000 ppm at 25 ºC. The potentiodynamic polarization study indicates that this compound acts as a mixed type corrosion inhibitor. The rate of corrosion of mild steel rapidly increases with temperature over the temperature range of 25 ºC to 55 ºC, both in absence and presence of the inhibitor. Thermodynamic parameter for adsorption process has been calculated using the Langmuir’s adsorption isotherm.
