Introduction: Natural plant polymers demonstrate effective corrosion inhibition abilities, because of their numerous binding sites and excellent adsorption abilities.Methodology: In this study, the Box-Behnken method, gravimetric and electrochemical analyses were used to design and investigate the corrosion inhibition potential of a modified graft polymer of okra for mild steel in a 1M HCl medium. The influence of inhibitor concentration, temperature, and time were also investigated. Qualitatively, the Fourier Transform Infrared (FTIR) spectroscopy, Thermogravimetric Analysis (TGA), and Field emission scanning electron microscopy (FESEM) were used to characterize the extracts and evaluate the metal’s surface morphology.Results and discussion: The quantitative analyses showed that the modified natural polymer’s inhibition efficiency (IE) increased with concentration and reached 73.5% at 800 ppm, with a mixed-type mode of inhibition. From the response surface methodology, it was revealed that temperature influences the IE more than concentration and immersion time. The optimized IE using the desirability function showed the possibility of attaining 88.2% inhibition with inhibitor concentration at 142.3 ppm, temperature at 60.4°C, and an immersion time of 22.4 h. The new functional groups in the hybrid polymer revealed by FTIR analysis shows that grafting improved the inhibitor’s adsorption abilities. TGA analysis confirmed the extract’s high thermal stability, which highlights the inhibitor’s strong adsorption and efficiency for high temperatures. FESEM analysis indicated evidence of inhibitor adsorption onto the metal surface.Conclusion: These findings suggest that the grafting of okra with acrylamide enhances its inhibition properties and contributes to its functionality as a cost-effective plant-based alternative inhibitor against corrosion for mild steel facilities.

“…The rice husk molecules' adsorption on the surface of the substrate could be attributed to a negatively charged acid anion (Cl -) from the HCl solution. Hence, the adsorption results in the surface coverage of the metallic material by preventing the corrosion of the substrate [24]. The metal surface protection occurs due to coordinated bond creation between the Al alloy and the rice husk inhibitor molecules [25,26].…”

This study investigated the inhibition characteristics of rice husk (RH) on corrosion of Aluminum 6061 in 1M hydrochloric acid. Gravimetric analysis and Scanning Electron Microscopy (SEM)/ Energy Dispersive X-ray analysis (EDX) as well as electrochemical studies revealed the potency of RH as a good inhibitor of the corrosion of Al 6061 in 1M HCl. Fourier Transform Infrared Spectroscopy (FTIR) indicated that –OH, C=C, and C=O with signals at (3317.19, 2932.9, 2848.2), (1631.8) and (1105.73, 1030.2, 447.15), respectively in RH were the viable active functional groups which adsorbed on the metal surface to effect reduction of corrosion rates. However, literature suggested the presence of amorphous silica in RH which served as a complimentary corrosion inhibitor. The corrosion current density of Al 6061 was reduced to 3.46 × 10−7 A/cm2 at 24 h as against 9.27 × 10−7 A/cm2 at the commencement of the potentiodynamic polarization measurements in inhibited 1M HCl. The control specimens exhibited an average corrosion rate of 3.86 × 10−6 A/cm2 in HCl solution at the start of this investigation as compared to the corrosion rate of 3.46 × 10−7 A/cm2 at 24 h of exposure in 5 mg RH- inhibited HCl. The obtained results gave a corrosion inhibition efficiency of about 90 to 92%.

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.
