摘要：Ethanolic extracts of Allium cepa L. seeds were investigated as green corrosion inhibitors for mild steel in 1 M HCl solution. Corrosion behavior was evaluated using weight loss measurements and electrochemical methods. Electrochemical techniques reveal that extracts exhibit excellent inhibition efficiency and act as mixed type inhibitor at the studied temperature (308 K). The inhibition efficiency was reached average values of 94.5% and 88% for mild steel in 1 M HCl solution containing (1 g/L) oilextracted by ethanol from the seeds of Allium cepa L.obtained from two regions in Morocco, Doukkala (EED), and Amposta (EET) respectively. Adsorption studies showed that the process follows Langmuir adsorption isotherm.
