“…In addition, it is observable that the effect of MBM (0.00162mpy) is better as compared to the M8151(0.00143mpy), which is being used in NUS cooling tower. The higher inhibition efficiency may be attributed to the increased electron density thus leading to electron transfer mechanism from functional group to metal surface, producing coordinate bonding with a greater adsorption and inhibition efficiency ( Beech et al, 1999 , Chauhan et al, 2021 ). This also agrees well with the finding that molybdate demonstrated little inhibition efficiency in view that the protective film formation is not favoured in electrolyte containing aggressive anions such as bromides ( Antonijevic et al 2009 ).…”

The present study has successfully identified the nitrate reducing bacteria present in the cooling water system and also investigated the performance of industrially applied biocide and inhibitor on the bacterial inhibition. In order to carry out the objective of this study, facilities and methods such as 16S rRNA gene sequencing, Lowry assay, SEM, EIS, ICP-MS and weight loss analysis were being utilized. In this study, two out of the five morphologically dis- similar colonies identified through 16S rRNA gene sequencing, namely the Massilia timonae and the Pseudomonas , were being utilized in the biocorrosion study on copper metal. From the surface analysis using SEM demonstrated the phenomenon of biofilm formation on the copper surface. 2-methylbenzimidazole has the addition of methyl group in the diazole ring position of benzimidazole it has create basicity environment and inhibit the metal deterioration. Meanwhile, it is also deducible from the EIS and protein analysis that com- bination of biocide with either of the inhibitors gives rise to better biocorrosion suppression (0.00178 mpy and 0.00171mpy) as compared to the sole effect of either biocide or inhibitor (0.00219 mpy, 0.00162 and 0.00143). Biocorrosion system biocide with MBM was found to exhibit 65% corrosion inhibition efficiency. Moreover, adoption of 2-Methylbenzimidazole seems to display better performance as compared to Multionic 8151, which is adopted in cooling water system.

“…Anti-corrosion coatings, corrosion-resistant alloys and corrosion inhibitors are just a few of the strategies used to combat corrosion damage. A corrosion inhibitor is a chemical additive that, when added in trace amounts to a corrosive environment, significantly reduces the corrosion rate without changing the concentration of the corrosive medium (Chauhan et al , 2021). Corrosion inhibitors are widely used in a variety of industries, including boilers, the sugar industry, oil and gas, the petroleum sector, water treatment plants, reactors, the energy sector and so on.…”

Purpose Plant development and use as green corrosion inhibitors are already recognized as one of the most environmentally friendly and effective protocols. In recent years, efforts have been made to find green corrosion inhibitors as an alternative to synthetic inhibitors for metals in acid medium. This paper aims to report the investigation of use of aqueous extracts of Tamarindus Indica as green inhibitors for corrosion of metals within different circumstances. Design/methodology/approach The use of Tamarindus Indica extracts (leaves, stem, fruit pulp and fruit husk) as corrosion inhibitors for mild steel and aluminum in different mediums (HCl, H2SO4, formic acid and citric acid) at different temperatures was investigated. Findings The inhibitory efficiency of Tamarindus Indica extracts increases with increasing concentration and decreases with increasing temperature. Langmuir is the adsorption isotherm, and the extract (inhibitor) is a mixed-type inhibitor (physisorption and chemisorption). Practical implications Tamarindus extracts (leaves, stem, fruit pulp and fruit husk) are effective inhibitors and can be used to protect metals from corrosion at different circumstances. Originality/value To the best of the authors’ knowledge, this is the first review that discusses the use of Tamarindus Indica extracts as corrosion inhibitors for metals.

“…Therefore, in all operations involving acidic solutions, equipment must be strictly protected. Although complete prevention of corrosion is impossible, it can be controlled using effective corrosion inhibitors (CIs). − CIs are chemical compounds that reduce the corrosion rate of metals at low concentrations when they are added to corrosive environments. They can be used in transportation, construction, energy, and industries owing to their economic efficiency and strong versatility. , Heteroatoms (such as N, O, P, and S), heterocycles, multiple bonds, and aromatic rings are the most important electron-rich groups in the structure of organic CIs that cause the adsorption of their molecules on the surface of metal and protect it against corrosive species in the medium. ,− In other words, the replacement of CIs with water molecules on the metal surface leads to the blocking of active sites for redox reactions and thus inhibits the transfer of water and corrosive ions on the metal surface. , The molecular properties of CI molecules, such as steric factors, aromaticity, chain length, functional groups, electronic structures, cross-linking ability, and solubility have a significant impact on their adsorption behavior .…”

Although corrosion inhibitors are widely used as a practical method for inhibiting metal corrosion in a variety of industries, their efficiency decreases dramatically at high temperatures. We present a thorough experimental and theoretical investigation into the inhibitory power of a novel thermally stable corrosion inhibitor based on furfuryl alcohol (FACI). The opencircuit potential, linear polarization resistance, potentiodynamic polarization, and electrochemical impedance spectroscopy techniques were used for the first time to evaluate FACI inhibition performance at 293, 313, 333, and 353 K. All electrochemical methods clearly indicated that FACI effectively suppressed corrosion of mild steel (MS) in the 15% HCl environment via a mixed-type mechanism at all temperatures investigated. The highest inhibition efficiencies of 95.4 and 90.8 at 333 and 353 K, respectively, were obtained in the solution containing 136 × 10 −5 M FACI. FACI inhibited both the anodic and cathodic corrosion reactions of MS, but its main effect was on the cathodic hydrogen evolutions. The results of the Langmuir adsorption isotherm confirmed that the predominantly chemical adsorption of FACI molecules occurred on the MS surface. The experimental results were also validated using a combined DFT.
