Description Praseodymium 4-hydroxycinnamate compound has been successfully studied as an effective corrosion inhibitor for carbon steel in 0.1 M NaCl solution using electrochemical techniques and surface analysis. The results of electrochemical techniques indicated that there were the decrease of current density and the appearance of protective film on the steel surface evidencing the presence of inhibitor and the effect of Pr(4OHCin)3 compound depending on its concentration in solution. The surface analysis show a confirmation of the protective film formation which is a result of adsorption between the metal and inhibitor components. In addition, inhibition performance of Pr(4OHCin)3 compound is also compared to the inhibition performance of TRACT 109, which has been added to a fresh cooling water system of Ca Mau fertilizer plant.
