Inhibition of the corrosion of mild steel in 1‐5 N HCl and H2SO4 by a macrocyclic compound viz., tetramethyl‐dithia‐octaazacyclotetradeca hexaene (MTAT) was studied as a corrosion inhibitor by weight loss and electrochemical potentiodynamic polarization methods. The influence of temperature, immersion time and acid concentration was also studied in the presence of MTAT in HCl and H2SO4. The potentiodynamic polarization carried out in 1‐5 N HCl and H2SO4 in the absence and presence of inhibitor revealed that MTAT is a mixed inhibitor. MTAT exhibited better performance as a corrosion inhibitor in H2SO4 and its performance was further improved the addition of KI due to synergism. The adsorption of MTAT on the mild steel surface obeyed Temkin adsorption isotherm.
