- •
Adsorption of the inhibitor on the metal surface is confirmed by thermodynamic data.
- •
Adsorption of the inhibitor onto the metal behaves according to the Langmuir model.
- •
Endothermic adsorption process indicates that the inhibitor is chemically adsorbed.
- •
The efficiency of corrosion inhibition was above 93%.
- •
The good performance of the corrosion inhibitor was maintained up to 24 h.
