Various concentrations of the inhibitor in 1 M HCl solution were tested, and the corrosion inhibition efficiency to mild steel was estimated by means of weight loss measurements, potentiodynamic polarization, and electrochemical impedance spectroscopy. The adsorption equilibrium constant (Kads) and standard free energy of adsorption (ΔG°ads) were calculated. The nature of inhibition was studied by various spectroscopic techniques such as UV–visible, FTIR, and EPR spectroscopies and by using surface analysis methods (i.e., SEM-EDS).

Anticorrosion potential of 4 - Amino - 3 - methyl - 1,2,4 - triazole - 5 - thione derivatives (SAMTT and DBAMTT) on mild steel in hydrochloric acid solution / Moorthy Saravana Kumar in Industrial & engineering chemistry research, Vol. 51 N° 15 (Avril 2012)

The results revealed that both SAMTT and DBAMTT act as excellent inhibitors, and the inhibition efficiencies obtained from the weight loss and electrochemical experiments were in good agreement. Scanning electron microscopic and atomic force microscopic images showed the efficiency of the compounds as inhibitors on mild steel in acid media, and both surface analysis techniques revealed that the inhibition occurs due to adsorption of the inhibitor molecules at the metal/solution interface.

Bisthiocarbohydrazones as colorimetric and “Turn on” fluorescent chemosensors for selective recognition of fluoride / Saravana Loganathan Ashok Kumar in Industrial & engineering chemistry research, Vol. 50 N° 22 (Novembre 2011) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 22 (Novembre 2011) . - pp. 12379-12383 Titre : Bisthiocarbohydrazones as colorimetric and “Turn on” fluorescent chemosensors for selective recognition of fluoride Type de document : texte imprimé Auteurs : Saravana Loganathan Ashok Kumar, Auteur ; Ramalingam Tamilarasan, Auteur ; Moorthy Saravana Kumar, Auteur Année de publication : 2012 Article en page(s) : pp. 12379-12383 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Bisthiocarbohydrazone  Heterocyclic Résumé : Bisthiocarbohydrazone derivatives of two heterocyclic ketones were designed and synthesized to selectively sense fluoride ion from a biologically competing solvent dimethylsulfoxide (DMSO). The selective recognition of fluoride is clearly visible to the naked eye with a distinct color change. The recognition mechanism has been investigated by UV–visible, fluorescence spectroscopy, and 1H NMR titration experiments. From the Benesi–Hidebrand equation and Job's plot, it was inferred that both compounds bind to fluoride with a 1:1 stoichiometry. 1H NMR titration data indicates deprotonation of the NH protons by fluoride as a prominent step in the recognition.
