Latest Exploration on Natural Corrosion Inhibitors for Industrial Important Metals in Hostile Fluid Environments: A Comprehensive Overview

Use of Cedrela odorata Linnaeus Exudate for Inhibiting Corrosion by Chlorides in Reinforced Concrete

“…These results illustrate that gummy cedar extract has a corrosion inhibiting effect, probably due to the formation of an adsorption film on the original passive layer on the surface of the reinforcing bar, as well as inside the mixture, which restricts the cathodic reaction. This property could be provided by phenolic and limonoid constituents, such as flavonoids and proanthocyanidins [43], which are responsible for the formation of the film [44] During the corrosive activity of ions, the gummy extract inhibited concrete corrosion by limiting the anodic reaction, a mechanism also provided by ginger extract [7], castor oil [19], Arabic gum [45], guar gum [46], and other green inhibitors [22], [25], [47], [48].…”

“…In this sense, cedar has been used as a coating on steel, obtaining corrosion inhibitions of up to 46.4 % [17]. Other elements that have been employed as anticorrosive agents include ginger extract [7], maize gluten meal [18], castor oil [19], cactus mucilage, marine brown algae, dehydrated cactus mucilage [20], apricot pomaces [15], Rhizophora mangle L. [9], [21], among others [22]- [25], because they contain compounds and functional groups that act as inhibitors of corrosive mechanisms. Therefore, the present article intends to evaluate the use of cedar exudate as an inhibitor of corrosion caused by the action of chlorides and the probability of steel corrosion in rc.…”

The Use of Rheum Ribes (Işgın) Extracts for Copper Protection in Acidic Media

“…Studies on the use of environmentally friendly molecules are being conducted in this field because the majority of organic inhibitors used are toxic and have negative effects on people and the environment [9][10][11][12]. Natural plant extracts have become popular for this purpose in recent years [13][14][15][16][17][18][19][20]. Natural plant extracts or active ingredients are natural and have no adverse effects on humans or the environment.…”

Inhibiting Effect of Natural Plant Leaves Extract Used as Green Corrosion Inhibitor for Mild Steel in Acidic Media

“…There are several advantages of these naturally obtained inhibitors. They are readily available, environmentally friendly, biodegradable, efficient, and renewable [20][21][22][23][24] .The present study designed to investigate the adsorption and inhibiting properties of plant extract of leaves of Bahunia Varigata (Aapta), Azadirachta Indica (Neem), Pongamia Pinnata (Karanj), Santalum Album (Sandal Wood) and Astonia Scholaris (Saptparni) for the corrosion of mild steel in 0.1, 0.01 and 0.001 N HCl solutions.…”
