The corrosion inhibition efficiency of an aqueous extract of adhatoda vasica leaves in controlling corrosion of mild steel immersed in well water has been evaluated by weight loss method. The mechanistic aspects of corrosion inhibition have been evaluated by electrochemical studies such as potentiodynamic polarization study and alternating current impedance spectra. The protective film formed on the metal surface has been analyzed by Fourier transforms infrared spectra, UV-visible absorption spectra and Fluorescence spectra. 10 mL of the inhibitor offers good corrosion inhibition efficiency. It is an environmentally friendly inhibitor.
