The influence of 4‐amino‐5‐mercapto‐3 n‐propyl‐1‐2‐4‐triazole (AMPT) on corrosion and hydrogen permeation through mild steel in 0.5M H2SO4 and 1M HCl has been studied using weight loss measurements and various electrochemical techniques. AMPT is found to be more inhibitive in H2SO4 than in HCl. Potentiodynamic polarisation studies clearly prove the fact that this compound behaves as a mixed inhibitor; but predominantly as a cathodic inhibitor. Hydrogen permeation studies and AC impedance measurements also indicate an improved performance of the compound in H2SO4. The adsorption of this compound on the mild steel surface obeys Temkin’s adsorption isotherm.
