“…The green inhibitors are heterocyclic with functional polar groups (-OH, -CH 3 , -OCH 3 , -NO 2 , and -COOH). The functional polar groups along conjugated π-electrons with double/triple bonds aid in adsorption, thereby, blocking cathodic and anodic reaction results in corrosion inhibition [56,[68][69][70][71].…”

Mangroves are plants known for their various medicinal and economical values, and therefore are widely investigated for their phytochemical, antioxidant, antidiarrheal, and antimicrobial activities. In the present study, we analyze the antioxidant and anticorrosive properties of Ceriops tagal (C. tagal), a tropical and subtropical mangrove plant of the Rhizophoraceae family. The total phenolic content (TPC) and total flavonoid content (TFC) were found to be 101.52 and 35.71 mg/g, respectively. The extract (100 µg/mL) exhibited 83.88, 85, and 87% antioxidant property against 1,1-diphenyl-2-picrylhydrazyl (DPPH), nitric oxide, and hydrogen peroxide free radicals. In addition, 600 ppm of C. tagal extract showed 95% corrosion inhibition against 1 M HCl attack on mild steel at 303 ± 1 K, which declined over other concentrations and temperatures, where AAS produced 82% inhibition at 600 ppm. UV-visible spectroscopy analysis revealed the formation of an inhibitor metal complex. The elemental analysis provided the presence of 84.21, 9.01, and 6.37% of Fe, O, and C, respectively, in inhibited mild steel, whereas the same were 71.54, 22.1, and 4.34%, respectively, in uninhibited specimen, stressing the presence of protective film on the metal surface. Scanning electron microscopy (SEM) also showed some noteworthy changes in both uninhibited and inhibited mild steel, making C. tagal plant a better alternative than any other synthetic inhibitors. Further, the atomic force microscopy (AFM) surface topography analysis showed that 600 ppm of C. tagal extract significantly diminished corrosion on the surface of mild steel.

“…The usefulness of the inhibitor depends mainly on its ability to adsorb on the metal surface [41,42] through either physisorption or chemisorption processes or a combination of both. [43] According to the parameters data, the increase in C dl is proportional to the decrease of extraction solvent polarity. Overall, the good performance of fruit extracts as inhibitors for mild steel in 1 M HCl solutions may be due to the presence of heteroatoms, πelectrons, and aromatic rings in their structures.…”

Phenolic compounds in Tunisian wild Rhus pentaphylla fruits during two maturity stages are identified by LC-MS-ESI. The corrosion inhibition efficiency of their extracts was analyzed by the use of polarization curves and electrochemical impedance spectroscopy. The qualitative analysis highlighted the presence of 11 phenolic compounds in total (3 phenolic acids and 8 flavonols) for the un-ripe stage (S1), 7 compounds (1 phenolic acid and 6 flavonols) have been identified for the fully-ripe stage (S2). The electrochemical behavior analysis of carbon steel in (1 M) HCl medium showed a maximum inhibition efficiency of 45.49 % was achieved by using 100 ppm of the inhibitor. Polarization studies indicate that the extracts act as a mixed inhibitor. As well, it has been shown that the first stage presents the highest inhibitory efficacy compared to the second. These results confirm the good correlation between the phytochemical composition and corrosion inhibition capacity.

Extracts of natural products are used as corrosion inhibitors since they are non toxic and environmentally friendly. Especially the extracts of leaves have attracted the attention of many researchers. Usually weight loss methods are adopted to measure the corrosion inhibition efficiencies. The mechanistic aspects have been investigated by electrochemical studies such as polarization study and AC impedance spectra. Sometimes noise measurement has also been used. The protective films formed on the metal surface have been analysed by surface analysis techniques such as SEM, EDAX, FTIR and AFM. Experiments have been carried out at various temperatures also. Various adsorption isotherms have been proposed. Of all the metals and alloys used, mild steel has been extensively used. The experiments have been carried out in acid medium and neutral medium (sodium chloride). The extracts of the leaves contain many ingredients which have polar groups such as N, O, S and P atoms. The lone pair of electrons present on these atoms are pumped on to the metal surface. This controls the corrosion process.
