Launaea nudicaulis as a source of new and efficient green corrosion inhibitor for mild steel in acidic medium: a comparative study of two solvent extracts
The inhibitive effect of Launaea nudicaulis methanolic (MLN) and aqueous acidic (ALN)
extracts on the corrosion of mild steel in 1.0 M HCl solution was investigated by using weight
loss, Tafel plots, linear polarization, electrochemical impedance spectroscopy (EIS) as well
as SEM and EDS techniques. It was found that both extracts (MLN and ALN) inhibit
remarkably the corrosion of mild steel in acidic solution and inhibition efficiencies increased
with the increase of extracts concentration. The results revealed that MLN and ALN behaved …
