چکیده مقاله:
۲,۲'-((۱Z,۱'Z)-(((propane-۱,۳-diylbis(oxy))bis(۲,۱-phenylene))bis(methanylylidene))bis(azanyly lidene))diethanol (۲-PPM) was synthesized. This compound evaluated as novel corrosion inhibitor for mild steel in ۱N H۲SO۴ solution. Polarization study showed that the compound was mixed type inhibitor. Electrochemical impedance study showed that the presence of this compound decreases the double layer capacitance and increases the charge transfer resistance.Weight loss study showed that, the corrosion inhibition property of ۲-PPM on the external area of mild steel samples in the solution is mainly depends on the inhibitor concentration and immersion period. Further, the maximum protection efficiency obtained by weight loss technique was ۶۵ %. SEM and AFM results fully support the chemical and electrochemical results.
