Özet
Through electrochemical impedance testing and potentiodynamic polarisation, it was investigated how a material at ambient temperature might prevent corrosion. 1-(5-(4-Methoxybenzoyl)-4-(4-methoxyphenyl)-2-oxopyrimidin-1(2H)-yl)-3-(4-chlorophenyl) urea (MMOP) was used as a corrosion inhibitor on mild steel samples in 1 M HCl. With a maximum inhibition efficacy of 97.6 % (at immersion period of 72 h and concentration of 5 × 10-4 M), the inhibitor used was shown to be an exceptional corrosion inhibitor. Based on the findings of potentiometric polarization, this substance falls within the category of mixed inhibitors since corrosion inhibition was accomplished by the inhibitor adhering to the metal. Adsorption of investigated MMOP completely followed Langmuir adsorption isotherm and adsorption can be categorized as physisorption–chemisorption, with a value of ΔGads of -35.6 kJ.mol-1. In order to confirm the …
