Utilization of watermelon rind extract as a green corrosion inhibitor for mild steel in acidic media

Hybrid nanocomposite from aniline and CeO2 nanoparticles: Surface protective performance on mild steel in acidic environment

“…6a, which exhibited one capacitive arc across the frequency range studied. It is well-known that the depression of the Nyquist semicircle for metal substrates is commonly designated as frequency dispersion and inhomogeneity of the electrode surface arising from the surface roughness or interfacial phenomena [24]. It was found from the Nyquist plots that the diameters of these capacitive arcs were increasing with PCN concentration.…”

Corrosion Inhibition of Carbon Steel in Acidic Environment by Papaya Seed as Green Inhibitor

“…These green inhibitors have been found to decrease the acid corrosion of mild steel by several folds with about 70-90% adsorption on the surface. Watermelon extract has been found [11] to have strong effect on corrosion of mild steel in HCl and H 2 SO 4 . The inhibition efficiency increases with the concentration of the extract increases.…”

Dry and wet lab analysis on benzofused heterocyclic compounds as effective corrosion inhibitors for mild steel in acidic medium

“…In addition, corrosion also has social implications such as health and safety of people working in industries or living nearby. The use of organic corrosion inhibitors constitutes one of the most economical and practical preventive maintenance methods to mitigate and control the corrosion rate, protect metal surfaces against corrosion and preserve industrial facilities [1,2]. A through literature survey reveals that most of the inhibitors act by adsorption onto the metal surface which takes place through heteroatoms such as N, O, P and S atoms, triple bonds or p electrons of aromatic rings which tend to form stronger coordination bonds.…”
