| Description |
Methanolic extract of Artemisia pallens was tested as corrosion inhibitor for mild steel in 4N HCl and
conc. HCl. Weight loss and polarization techniques were used for evaluating corrosion inhibition in 4N
HCl, whilst weight loss, SEM and FT-IR studies were carried out in conc. HCl. The inhibition efficiency
was found to increase with increase of the inhibitor concentrations due to the adsorption of the inhibitor
molecules on the metal surface and the adsorption follows Langmuir’s adsorption isotherm. The inhibition
efficiency was found to be 93% at 1.5 g l−1 in 4N HCl and 96.5% at 40 g l−1 in conc. HCl.
