Paper Title:
Inhibition Action and Adsorption Behavior of 3-Amino-1,2,4-Triazole on Copper in 3% NaCl Solution
  Abstract

The corrosion inhibition of copper in 3% NaCl solution by 3-amino-1, 2, 4-triazole (ATA) has been studied in relation to the concentration of the inhibitor using electrochemical (AC impedance and dc polarization) techniques. The results indicate that ATA has good corrosion inhibition for copper in 3% NaCl solution. The inhibition efficiency attains the maximum value of 97.65% when the concentration of ATA is 20 mg•L-1.Polarisation curves show that ATA behaves as a type of cathodal inhibition in 3% NaCl solution. Adsorption of the ATA is found to follow the Langmuir’s adsorption isotherm, and the adsorption mechanism is typical of chemisorption.
