Analysis of protective (Nano) film of Ocimum tenuiflorum (tulsi) extract by surface examination study

Author(s): D. Madhan and P. Rajkumar

Tulsi was evaluated as corrosion inhibitor of steel in molar hydrochloric acid in sea water using weight loss measurements, electrochemical polarization and EIS methods. The tulsi (eugenol) was found to retard the corrosion rate of steel. Tulsi 10g / 100mL(8mL / 100 mL) gives 90% inhibition efficiency. The surface morphology of the protective film on the metal surface was characterized by using Scanning Electron Microscopy (SEM) and atomic force microscopy (AFM).
