“…3b), it can be observed that the adsorption of NMS molecules on carbon steel surface can be achieved by: (1) weak bonds (hydrogen bridges) through -OH and -NH2 groups from NMS molecule and carbon steel surface, suggesting physical adsorption; (2) chemical bonds between the unshared electron pairs from the oxygen atom of the tetrahydropyrane (oxane) ring or from the oxygen atom that binds two tetrahydropyranyl rings and dunoccupied orbital of iron atom, indicating chemical adsorption; (3) also, the complexes of neomycin-iron ions [19] can be adsorbed onto the steel surface through Van der Waals bonds [5]. Thus, there is a synergism between the physical and chemical adsorption and consequently, adsorption mixed mechanism of neomycin molecules on carbon steel surface takes place, this being confirmed by the ΔG o ads value [23,24].…”

“…The experimental data listed in Table 1 shows that NMS behaves as corrosion inhibitor for carbon steel, in 1.0 M H2SO4 at the room temperature. The following arguments support this statement: (i) the increase of the NMS concentration leads to icorr breakdown while Rct increases and Cdl decreases; (ii) IE follows the same increasing trend as the inhibitor concentration; (iii) the NMS inhibition action is due to the adsorption of its molecules on carbon steel surface, contributing to formation of a surface protective layer [23][24][25][26].…”

“…Also, Table 1 shows the inhibition efficiency (IE) calculated as a function of (icorr) and (Rct), as shown the Equation 6 and 7 [20,[23][24][25]. (7) where: i o corr and R o ct are the corrosion current density and charge-transfer resistance, respectively computed for the carbon steel corroded in 1.0 M H2SO4 blank solution, icorr and Rct represent the corrosion current density and charge-transfer resistance, respectively, computed for carbon steel corroded in 1.0 M H2SO4 solution containing various NMS concentrations.…”

Our study aims to implement a strategy to reduce the carbon steel corrosion rate in sulfuric acid solution, using an expired drug with adsorption affinity on the metal surface. To investigate the corrosion protection efficiency of an environmental friendly inhibitor, namely neomycin sulfate (NMS), the electrochemical measurements were applied on carbon steel immersed in 1.0 M H2SO4 solution with and without NMS. The protective layer formed on the steel surface was studied by atomic force microscopy (AFM). The potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) showed that the presence of the neomycin sulfate in acid solution leads to the decrease in corrosion current density (icorr) and the increase of polarization resistance (Rp). The mixed mechanism between physical and chemical adsorption of NMS molecules on the steel surface was proposed according to the Langmuir adsorption isotherm. The Atomic Force Microscopy (AFM) indicated that the NMS molecules contributed to a protective layer formation by their adsorption on the steel surface. The AFM parameters such as: rootmean-square roughness (Rq); average roughness (Ra) and maximum peak to valley height (Rp-v) revealed that in the presence of NMS a smoother surface of carbon steel was obtained, compared to the steel surface corroded in sulfuric acid blank solution.

Complexes of cobalt(II), nickel(II) and copper(II) of l‐histidine Schiff base derived from 2,4‐dihydroxybenzaldehyde and 2‐hydroxy‐1‐naphthaldehyde have been synthesized. The structures of ligands and complexes have been characterized using elemental analysis, molar conductance, magnetic moment measurements, and spectral and thermal studies. The ligands behave as tridentate, coordinating through the azomethine nitrogen and α‐hydroxyl and carboxylic oxygen atoms. The obtained results show that the Cu(II) complexes have square planar geometry, the Co(II) complexes have octahedral and tetrahedral geometries and the Ni(II) complexes have square planar and octahedral geometries. The molecular geometries of the metal complexes are supported by three‐dimensional molecular modelling using molecular mechanics (MM+) and semiempirical molecular orbital calculations (PM3). The inhibition effect of ligands and complexes on the corrosion of aluminium in 2 M H2SO4 was investigated using weight loss. The inhibition efficiency is found to increase with increasing inhibitor concentration and temperature. The increase in inhibition efficiency with increasing temperature is suggestive of a chemical adsorption process. Copyright © 2014 John Wiley & Sons, Ltd.

Corrosion is a phenomenon that devastatingly affects innovative, industrial, and mechanical applications, especially in the oil and gas industries. The corrosion conceivably influences industrial equipment; it deteriorates the environment and lessens the equipment/infrastructure's lifetime. Considering the significant impact of corrosion in our daily lives, this review article aims to briefly discuss the significance of corrosion and different control methods with special attention on corrosion inhibitors. The classification of corrosion inhibitors based on types and their advantage/ limitations, and heterocyclic compounds as potential corrosion inhibitors, mainly nitrogen-based compounds (pyridine (1N), pyrimidine (2N), and triazines (3N) fused ring benzimidazole, etc.), and their biological significance has been discussed in detail. The mechanism, challenges, and applications of heterocyclic compounds as corrosion inhibitors in various industrial relevant corrosive environments such as acid pickling, descaling operation in the desalination plant, oil gas industry, etc., have also been highlighted in the review.
