Abstract  

The corrosion behavior of copper in the presence of 3-amino-5-mer capto-1,2,4-triazole (3-AMT) has been investigated in deionized water. Potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and weight-loss measurement were applied to analyze the effect of the organic compounds on the corrosion inhibition of copper. Results showed that the inhibition efficiency increased with increasing the inhibitor concentration and the compound acted at anodic-type inhibitor. The adsorption of 3-AMT has been found to occur on the surface of copper according to the Langmuir isotherm. 3-AMT is chemically adsorbed on the copper surface.
