Type: article
Abstract: The inhibitory ability of boiling extracts from the fallen leaves of Fagus sylvatica purpurea on the corrosion of mild steel EN Fe37-3FN in 0.5 M hydrochloric acid and 0.5 M sulphuric acid media was investigated using gravimetric, electrochemical, and EIS methods. The results show that the addition of 100 mg/L of Fagus sylvatica purpurea fallen leaf extract reduces the corrosion rate by 20–25%, while the addition of 1 g/L or more reduces it by 65–70%. The adsorption of the extract components on the steel surface follows the Langmuir adsorption model, and the nature of the adsorption is physical. The Fagus sylvatica purpurea fallen leaf extract demonstrates potential as an environmentally friendly substance for reducing steel corrosion rates in acidic environments.
