Electroanalytical and theoretical investigations of the corrosion inhibition behavior of Bis-1,2,4-triazole precursors EBATTand BBATT on mild steel in 0.1 N HNO3. / Sam John in Industrial & engineering chemistry research, Vol. 51 N° 51 (Décembre 2012) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 51 (Décembre 2012) . - pp. 16633-16642 Titre : Electroanalytical and theoretical investigations of the corrosion inhibition behavior of Bis-1,2,4-triazole precursors EBATTand BBATT on mild steel in 0.1 N HNO3. Type de document : texte imprimé Auteurs : Sam John, Auteur ; Abraham Joseph, Auteur Année de publication : 2012 Article en page(s) : pp. 16633-16642 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Mild  steel  Precursor  Corrosion  inhibition Résumé : The inhibition of mild steel corrosion in 0.1 N nitric acid by the bis-1,2,4-triazole precursors EBATT and BBATT was investigated by potentiodynamic polarization (Tafel), electrochemical impedance spectroscopy (EIS), adsorption, and quantum chemical calculations at 300 K. Polarization studies showed that these molecules act as mixed-type inhibitors. As the electron density around the inhibitor molecules increases due to substitution, the inhibition efficiency also increases. The quantum chemical approach was also used to calculate electronic properties of the molecules to ascertain the correlation between inhibition effect and molecular structure. Experimental and theoretical studies agree well in this regard and confirm that BBATT is a better inhibitor than EBATT.
