Natural Elettaria cardamomum Essential Oil as a Sustainable and a Green Corrosion Inhibitor for Mild Steel in 1.0 M HCl Solution: Electrochemical and Computational Methods

Effective corrosion inhibition of mild steel in hydrochloric acid by newly synthesized Schiff base nano Co(ii) and Cr(iii) complexes: spectral, thermal, electrochemical and DFT (FMO, NBO) studies

“…2 The losses cost could be estimated to billions of dollars every year. 3 Several methods and techniques were developed to resist the corrosion of metals like deposition and coating, [4][5][6][7] however the application of corrosion inhibitors still one of the most suitable and effective methods. 8,9 Corrosion inhibitors are characterized by high degree of adsorption ability onto metallic surface.…”

Corrosion Inhibition of Elettarai cardamom Bark Extract on Mild Steel in 1M H2SO4

“…The various parts of plant extract are used as green corrosion inhibitors to protect metals and alloys from their surroundings. Lantana camara (Shrestha et al, 2019), Euphorbia royleana (Thapa et al, 2019), Artemesia vulgaris (Karki et al, 2018), Jatropa curcas (Gupta, Kafle, et al, 2020) Eucalyptus globulus (Gupta, Awasthi, et al, 2020) Equistem helyme (Karki et al, 2021) Elettarai cardamomum (Tarfaoui et al, 2021) extracts have been investigated as a green corrosion inhibitor, ISSN NO. 2392-4624 COGNITION A Peer Reviewed Transdisciplinary Research Journal which shows adequate corrosion protection with high inhibition efficiency.…”

“…Plant extracts of cardamom (dried stems, leaves) and other high-altitude plants were used in H2SO4 pickling baths as early as 1930 (Gellings, 1985). The effectiveness of Elettaria cardamomum essential oil (EO) was studied by Tarfaoui et al (2021) as an inhibitor for MS in 1.0 M HCl by potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), and computational studies. The result showed that the essential oil prevented mild steel corrosion, and its prevention efficacy rose with concentration.…”

“…In contrast, the growth of a film on the brass surface is due to the adsorption of these molecules on the alloy. The pharmacological effects of these plants essential oil reveal antioxidant, anti-diabetic, antibacterial, anti-cancer, gastro-protective, and insecticidal properties (Ahmed et al, 2019;Tarfaoui et al, 2021). Asthma and cardiovascular disease are treated using Elettaria cardamomum's fragrant seeds.…”

“…Asthma and cardiovascular disease are treated using Elettaria cardamomum's fragrant seeds. 1,8-cineole, α-terpinyl acetate and linalool are the main compounds (Ashokkumar et al, 2020;Tarfaoui et al, 2021). Since the active ingredient's composition determines how green inhibitors work, numerous researchers have proposed various theories to account for this occurrence.…”
