“…Their results showed that increasing the rosemary extract concentration to 800 ppm enhanced the corrosion inhibition efficiency to 92.0% 24 . Moreover, exploration of the inhibition performance of other plant extracts, including Mish Gush 25 , Xanthium strumarium 26 , Eriobotrya japonic a Lindl 27 , Cardaria draba 28 , Urtica dioica 29 , Arbutus unedo L 30 , Euphorbia heterophylla L 31 and Thymus vulgaris 32 , Onion–garlic 33 obviously endorsed the potential of plant extracts as corrosion inhibitors.…”

Undoubtedly, metal corrosion is one of the most challenging problems faced by industries. Introducing corrosion inhibitors is a reasonable approach to protecting the metal surface. Due to environmental concerns and the toxicity of industrial organic corrosion inhibitors, researchers are continually exploring acceptable replacements. The current study focused on the application of Falcaria Vulgaris (FV) leaves extract to mitigate mild steel (MS) corrosion in a 1 M HCl environment. The polarization findings demonstrated that the corrosion current density decreased from 264.0 µA/cm2 (for the sample submerged in the blank solution) to 20.4 µA/cm2 when the optimal concentration of 800 ppm of FV leaves extract was added to the acid solution. Electrochemical impedance spectroscopy (EIS) analysis revealed an inhibition efficiency of 91.3% at this concentration after 6 h of immersion. It was determined by analyzing several adsorption isotherms that this corrosion inhibitor obeys the Frumkin isotherm. AFM, FE-SEM, and GIXRD surface analyses also supported the findings that adding FV leaves extract can reduce metal damage by adsorption on the metal surface.
