Inhibition effect of amino acid derivatives on the corrosion of brass in 0.6 M aqueous sodium chloride solution
The inhibitive effects of three amino acids and their benzenesulphonyl derivatives against the corrosion of brass in 0.6 M aqueous sodium chloride solution have been studied using potentiodynamic polarization and electrochemical impedance spectroscopy. The amino acids used are glycine (I), L (-) aspartic acid (II) and L (-) glutamic acid (III) and their corresponding benzenesulphonyl derivatives IV, V and VI. The inhibition efficiency of these compounds increases in the order I
