A method for inhibiting corrosion of a metal article in contact with a solution including an acid includes adding to the solution a corrosion inhibitor in an amount of 1 to 500 parts per million (ppm) based on the total number of parts by mass of the solution, thereby adsorbing the corrosion inhibitor onto the surface of the metal article via at least one interaction to form a barrier layer in the form of a composite. The at least one interaction comprises a physisorption, a chemisorption, and a retro donation. The corrosion inhibitor has a formula (I) where n is any integer from 8 to 21 inclusive and R, R, R, R, and Rs are each independently selected from the group consisting of a hydrogen atom, a hydroxyl group, an optionally substituted alkyl, an optionally substituted cycloalkyl, and an optionally substituted alkoxy.
