“…Syringic and vanillic acids as well as some phenolic compounds (such as 4-hydroxy-3-methoxybenzoic acid, 3,4-dihydroxybenzoic acid and 3-acetyl-4-hydroxy-5-methoxybenzoic acid) which have also been found in the extract and are essential contributors to the corrosion inhibition effect of the mango peel extract [59]. Other studies with good maximum inhibition efficiencies (%IE) have also been reported for mango peel extract including 87.77% [60], 97% [61], 91% [62], etc. In Table 3, we summarised some fruit peels that are active as corrosion inhibitors.…”

Current successes recorded in the use of plant leaves as corrosion inhibitors have been globally admitted as one of the best options. Little attention is paid to the future implication or risks concerning food insecurity, economic challenges and competition in various sectors that employ plants as their raw materials. This study reviewed the potential of plant wastes (such as peels, rinds and other components) as alternative sources of sustainable corrosion inhibitors. The review reveals that through the considerations of experimental and quantum chemical data as well as their chemical constituents, most plant wastes have excellent corrosion inhibition capacity. Those tested and confirmed as good corrosion inhibitors have also been reviewed. Computational chemistry has been implemented to demonstrate how some challenges confronting the understanding of their inhibition mechanism can be resolved.

“…They stated that, an increase in inhibitor or extract concentration, will increase the efficiency of corrosion inhibition. The corrosion inhibition efficiency of steel API 5L grade B by mango peel extract at 25 ºC was 81.77 % [36]. A study on corrosion of carbon steel inhibited in 400 ppm in 1 M HCl was given an inhibition of 80 % for 4-hour immersion [37].…”

Nowadays, researchers are interested in exploring the possibility of replacing harmful inorganic chemicals with green organic substances derived from natural sources. This study focuses on accessing the potential of a green corrosion inhibitor for mild steel, using plant extracts from local mango peel. The Harumanis mango peel leftover was extracted using solvent extraction techniques and the chemical compounds were characterized through Fourier Transform Infra-Red (FTIR) and UV-visible spectroscopy. The analysis showed that the crude extract of Harumanis mango peel (HMPE) contained active functional groups for corrosion inhibitory properties such as -OH, -COOH, -C=O and aromatic ring structure. The presence of mangiferin and other flavonols, likely acid gallic, was also detected. The efficiency of HMPE as a corrosion inhibitor for mild steel was investigated through a conventional corrosion test. The immersion test was carried out in different temperatures at 30, 40, 50 and 60 ⁰C with and without the addition of the 50 to 350 ppm HMPE inhibitor in 1 M hydrochloric acid, HCl. The result showed that the corrosion inhibition efficiency for mild steel in acidic medium increased as the concentration of the Harumanis mango peel increased. The maximum inhibition efficiency of 85 % was obtained at 30 ⁰C for 300 ppm. The adsorption of the Harumanis mango peel corrosion inhibitor obeys Langmuir isotherm model. The adsorption of HMPE on mild steel showed comprehensive (mixed) types as revealed by thermodynamic studies. Favourable adsorption was more dominant for 30 and 40 ºC inhibitors system, whereas at high temperatures the adsorption showed weak and unfavourable interaction between HMPE and the mild steel surface. Surface analysis showed the mild steel surface was free from pits and uniform corrosion as it was inhibited by the HMPE in low temperature solution.

“…The higher the current obtained, the higher the corrosion rate. [7] This method is done by immersing metal specimens into corrosive media. This aims to determine the corrosion rate based on the weight loss of the material corroded in the corrosion medium.…”

Corrosion is the process of natural changes in the nature of a material due to the influence or reaction with the surrounding environment. One way to control it is by adding inhibitors. In this study, seeds from guava (Psidium Guajava) were used as organic inhibitors. The test material used is API 5L grade B steel. For corrosive media, a solution of 1 M H2SO4 is used. In experiments used variations in the concentration of extracts 0, 2, 3, 4, 5 and 6 ml. The results of the experiments showed a decrease in the corrosion rate of API 5L grade B when there were additional inhibitors. This is supported by the experimental results of Potentiodynamic Polarization. The rate of corrosion without the presence of an inhibitor shows 75,018 mmpy whereas in the presence of 2,8845 mmpy inhibitors. Based on the calculation, the inhibition efficiency is 96.155%. This is also indicated by the results of the testing of weight loss that has been done. The efficiency shown is 90.130%.
