    The effect of 3,5-bis (2-thienyl) -4-amino-1, 2,4-triazole (2-TAT) on corrosion inhibition of copper was studied in 1 molL-1 HC1 by polarization curves and electrochemical impedance spectroscopy. The electrochemical study reveals that the compound is a cathodic-type inhibitor. Changes in impedance parameters are the indication of adsorption of 2-TAT on the copper surface,leading to the formation of a protective film. The adsorption of 2-TAT obeys the Langmuir adsorption isotherm.
