•: 10">Adsorption of the inhibitor on the metal surface is confirmed by thermodynamic data.
•: 15">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.
