Abstract
New 1, 2, 4-triazole derivatives have been synthesized and their anticorrosion properties established. The structures of these compounds were confirmed by spectral studies. The corrosion inhibition of mild steel in 0.5M HCl by the three derivatives at 0.01–0.05gL−1 was studied using mass loss and electrochemical techniques. Corrosion inhibition mechanism was proposed based on activation and adsorption thermodynamic parameters. Scanning electron microscopy exhibited the film formed on the metal surface. The electronic properties of the inhibitors were obtained from Hyperchem 7.5 package program. Excellent correlation was found between theoretical and experimental results.
