The chemical technique was used to investigate the inhibition and adsorption properties of L-proline for steel corrosion (weight loss method). As the concentration of L-proline increased, the inhibition efficiency increased, but decreased as the temperature increased, according to the findings. The inhibitor’s adsorption to the steel surface has been shown to be random, involving both electrostatic and chemisorptions. The Temkin adsorption isotherm governs the adsorption of L-proline to the steel surface. Thermodynamic parameters have been determined in some cases.
