Abstract: In chemical manufactures, the corrosion inhibitors were added in order to reduce the corrosion of mild steel. Chemical molecules are often used on mild steel surfaces as portion of the latest finishing steps before painting and/or storage. Here, this work elucidated the utilization of an isatin derivative, namely, 3-((3-acetylphenyl)imino)indolin-2-one synergistic with zinc oxide nanoparticles for improving the impedance of mild steel (MS) against corrosion in 1.0 M hydrochloric acid using the weight loss method and scanning electron microscopy (SEM). Weight loss measurements demonstrated that the best 3-((3-acetylphenyl)imino)indolin-2-one concentration was 0.5 mM and the inhibition efficiency was 83% whereas the inhibition efficiency was 92% with addition of ZnO NPs. 3-((3-Acetylphenyl)imino)indolin-2-one retards the corrosion process at 300 K and demonstrates low inhibition efficiencies at 310, 320 and 330 K.
