Acteoside: a novel green inhibitor for the corrosion of copper in 1.0 M HNO₃ solution: experimental and theoretical investigation.

ABSTRACT: Acteoside (ACT) isolated from A. orientalis L. was investigated as a corrosion inhibitor of copper in 1.0 M HNO₃ acid solutions using conventional weight loss, electrochemical polarization, and electrochemical impedance spectroscopy (EIS) studies. The molecular structure of acteoside (ACT) is supported by all the experimental results from LC-MS, FT-IR, ¹H, and ¹³C-NMR. The findings indicate that ACT is a potent inhibitor, and that its effectiveness increases with both temperature and inhibitor concentration. The highest inhibitor concentration occurs at 48 °C, and the inhibition efficiency peaks at 98.8%. The results indicated that the presence of the inhibitor slightly lessened copper dissolution with rising temperature. ACT adheres to the Langmuir,
