Abstract :

The anti-corrosion behavior of Phyllanthus Niruri leaves extracts in Well water solution on mild steel were studied using gravimetric method (weight loss method), FTIR spectroscopy and scanning electron microscope(SEM) techniques. The extracts were shown to have good inhibition efficiencies for the gravimetric method. Synergistic effect exists between the Phyllanthus Niruri - Ni2+ system in controlling the corrosion of mild steel immersed in Well water in the absence and presence of Ni2+. The formulation consisting of 250 ppm Phyllanthus Niruri, 20 ppm of Ni2+ have 90% inhibition efficiency. A more stable and compact protective film formed on the metal surface. The FT-IR and SEM analysis reveal that the protective film is formed on the metal surface.
