Abstract: Corrosion inhibition of mild steel in carbonated drinks solutions of Coca-Cola, sprite and Fanta using plant extract of Chrysohllym albidium (CA) was investigated at ambient (25°C), fridge (5°C) and freezer (-3°C) temperatures by gravimetric techniques. There was a characteristic observation of high inhibition efficiencies of 93.8% at 5°C in Fanta, 90.0% in Sprite at -3°C and 92.7% in Coke at -3°C. It was deduced that weight loss reduced as the temperature decreased. Scanning electron microscopy (SEM) micrographs revealed that CA actually inhibited corrosion of mild steel when the surface morphology of the inhibited and uninhibited metal coupon were compared. The result shows that these inhibitors are effective as corrosion inhibitors for mild steel in these carbonated drinks. Scanning electron microscopy result shows that the surfaces of the metals were quite protected in the presence of these inhibitors, with evidence of adsorbent species on its surface.
