Abstract: The use of human black hair (HBH) extract as corrosion inhibitors of mild steel in 1 M H2SO4 medium has been studied using weight loss, potentiodynamic polarization, electrochemical impedance spectroscopy. The results show the corrosion inhibition efficiency increased on increasing the concentration of the inhibitor. The extract is s a mixed type inhibitor with optimum concentration of 0.040% v/v in potentiodynamic polarization. The adsorption characteristics of the inhibitors have been determined from the results. Scanning electron microscopy (SEM) study confirm that the inhibition of corrosion of mild steel is through adsorption of the extract molecules on surface of metal.
