“…Heterocyclic organic compounds containing nitrogen, sulphur or oxygen atoms are often used to protect metals from corrosion. For the past few years, azoles have been intensively investigated as effective corrosion inhibitors [11][12][13][14][15][16][17] for various environments.…”

3,5-Diamino-1,2,4-triazole Schiff base derivatives and their inhibition efficiency, based on the effect of changing functional groups, were reported to establish a relationship between inhibitor efficiency and molecular structure using weight loss method, electrochemical and Fourier transform infrared spectral techniques. It was found that the molecules containing more electron donating groups have higher inhibition efficiency than the corresponding compounds with low electron donating groups.The results indicate that the order of inhibition efficiency of the triazole and its Schiff bases in solution and the extent of their tendency to adsorb on mild steel surfaces are as follows: vanilidine 3,5-diamino-1,2,4-triazole [ furfuraldine 3,5-diamino-1,2,4-triazole [ anisalidine 3,5-diamino-1,2, 4-triazole [ 3,5-diamino-1,2,4-triazole.

“…Such a barrier is readily formed by nitrogen‐containing heterocyclic molecules because of strong π‐interaction between the aromatic rings . Earlier studies claimed that the presence of cuprous oxide facilitates the initial physisorption of benzotriazole . According to our previous investigation, it is inferred that the benzotriazole derivatives get adsorbed on copper surface.…”

f 1-(2-Pyrrole carbonyl) benzotriazole (PBTA) and 1-(2-thienyl carbonyl)-benzotriazole (TBTA) were synthesized. Different concentrations of PBTA, TBTA, sodium dodecyl sulphate (SDS), and molybdate (Mo) were evaluated as corrosion inhibitors for copper in ground water medium at different temperatures. The obtained results were compared with the effect of benzotriazole (BTA) on the inhibition of copper corrosion at the same condition. The study was performed using potentiodynamic polarization, electrochemical impedance spectroscopy, cyclic voltammetry, and scanning electron microscopy investigations. A good inhibition is ensured at elevated temperatures. All measurements indicated that PBTA, TBTA, and BTA act as good corrosion inhibitors and their inhibition efficiency (IE%) increased with combining them with optimum concentration of SDS and Mo. Furthermore, the best performance was recorded for the compound PBTA + SDS + Mo, which was found to offer increased IE% in a synergistic manner, thereby acting as a good corrosion inhibitor for copper in ground water medium.

“…Several methods have been investigated and implemented to reduce the corrosion process and extend the lifetime of the metals/structures including painting, electroplating, coating, and cathodic protection [5][6][7][8][9]. The use of inhibitors has been found to be one of the best options available for the protection of metals against corrosion [10].…”

A comparative study of the inhibitory potentials of gum exudates from Albizia ferruginea (AF) and Khaya senegalensis (KS) on the corrosion of mild steel in HCl medium was investigated using weight loss and gasometric method. The active chemical constituents of the gum were elucidated using GC-MS while FTIR was used to identify the bonds/functional groups in the gums. The two gum exudates were found to be good corrosion inhibitors for mild steel in acidic medium. On comparison, maximum inhibition efficiency was found in Khaya senegalensis with 82.56% inhibition efficiency at 0.5% g/L concentration of the gum. This may be due to the fact that more compounds with heteroatoms were identified in the GCMS spectrum of KS gum compared to the AF gum.The presence of such compounds may have enhanced their adsorption on the metal surface and thereby blocking the surface and protecting the metal from corrosion. The adsorption of the inhibitors was found to be exothermic and spontaneous and fitted the Langmuir adsorption model.
