摘要	The adsorption behavior and corrosion inhibition mechanism of three amino acids have been studied by using weight loss, electrochemical test, scanning electron microscope, quantum chemical calculation and molecular dynamics simulation techniques. Gravimetric and electrochemical results showed the inhibition efficiencies both increased with the increasing L-arginine and L-lysine concentration from 1.0 g.L-1 to 10.0 g.L-1, the maximum inhibition efficiency 74.1% and 69.1% was obtained, respectively. However, the inhibition efficiency changed slightly with the increasing concentration of L-histidine. The adsorption behaviors of three amino acids obeyed the Langmuir isotherm and more details were given by theoretical calculation.
