Adsorption and corrosion inhibition behavior of mild steel by one derivative of benzoic−triazole in acidic solution / Zhihua Tao in Industrial & engineering chemistry research, Vol. 49 N° 6 (Mars 2010) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 49 N° 6 (Mars 2010) . - pp. 2593–2599 Titre : Adsorption and corrosion inhibition behavior of mild steel by one derivative of benzoic−triazole in acidic solution Type de document : texte imprimé Auteurs : Zhihua Tao, Auteur ; Shengtao Zhang, Auteur ; Weihua Li, Auteur Année de publication : 2010 Article en page(s) : pp. 2593–2599 Note générale : Industrial Chemistry Langues : Anglais (eng) Mots-clés : Adsorption  Corrosion  Inhibition  Behavior  Mild  Steel  Benzoic  Triazole  Acidic Résumé : A newly synthesized benzoic−triazole derivative 3,5-dimethylbenzoic acid [1,2,4]triazol-1-ylmethyl ester (DBT) was investigated as a corrosion inhibitor of mild steel in 1 M HCl solution using weight loss measurements, potentiodynamic polarization, SEM, and EIS methods. The results revealed that DBT was an excellent inhibitor, and the inhibition efficiencies obtained from weight loss and electrochemical experiments were in good agreement. Using the potentiodynamic polarization technique, the inhibitor was proved to have a mixed-type character for mild steel by suppressing both anodic and cathodic reactions on the metal surface. The number of water molecules (X) replaced by a molecule of organic adsorbate was determined from the Flory−Huggins, Dhar−Flory−Huggins, and Bockris−Swinkels substitutional adsorption isotherms applied to the data obtained from the gravimetric experiments performed on a mild steel specimen in 1 M HCl solution at 298 K.

Adsorption and inhibitory mechanism of 1H-1,2,4-triazol-l-yl-methyl-2-(4-chlorophenoxy) acetate on corrosion of mild steel in acidic solution / Zhihua Tao in Industrial & engineering chemistry research, Vol. 50 N° 10 (Mai 2011)

The potentiodynamic polarization measurements show that the TMCA acts essentially as a mixed-type inhibitor, and EIS confirmed that changes in the impedance parameters were due to surface adsorption. The inhibition efficiencies (IE%) obtained from weight loss measurement and electrochemical tests were in good agreement. Substitutional inhibition mechanism of mild steel was established according to the fitted results at different temperatures. The number of water molecules (X) replaced by a molecule of organic adsorbate was determined from the different substitutional adsorption isotherms applied to the data obtained from weight loss experiments.
