Abstract
The corrosion inhibition of mild steel in 1 M hydrochloric acid solutions by aqueous extract of Lavandula dentata (LD) was investigated using chemical (weight loss) and electrochemical (potentiodynamic and electrochemical impedance spectroscopy, EIS) measurements. The results from these techniques show that the inhibition efficiency increases with increase in the percentage of LD extract to attain 95% at 2wt%. Polarization studies indicate that the phytochemical compounds present in LD extract acts as a mixed type inhibitor in 1 M HCl solution.
