Chrysoidine Dye as a Novel Corrosion Inhibitor for Mild Steel in Acidic Solutions

Abstract

Abstract- Chrysoidine dye was examined as an inhibitor for mild steel in 1N HCl using weight loss, gasometric and thermometric methods. Parameters such as inhibition efficiency and corrosion rates were evaluated. The inhibition efficiency was found to increase with increase in the inhibitor concentration. To study the adsorption of the inhibitor on the mild steel surface, adsorption isotherm was plotted. Weight loss, gasometry and thermometric studies were carried out as reported earlier 12-16. From the weight loss experiments the % inhibition efficiency (I.E) and the degree of surface coverage (θ) were calculated by using the following equations.
