Inhibitive Performance of Ibuprofen Drug on Mild Steel in 0.5 M of H2SO4 Acid

The search for eco-friendly inhibitors has necessitated the use of inhibitive drugs in the control of corrosion in aggressive environments. This work examines the adsorption effect of Ibuprofen drug as on mild steel in H2SO4 environment using polarization method. The Ibuprofen drug was administered in the proportion of 0, 5, 10, 15, and 20 ml. The adsorption studies unveiled that as the Ibuprofen drug concentration increases, the inhibition efficiency of the inhibited samples increases. The result shows that the inhibitive drug offered some degree of protection on the steel in the corrosive medium. The inhibitor efficiency was above 60%. The adsorption of the inhibitive drug was found to obey Freundlich isotherm law with correlation regression coefficient of R2 = 0.9676. The closeness of R2 to unity establishes the reliability of Ibuprofen drug as inhibitor.
