Abstract :
Pulverised ginger rhizome was studied as corrosion inhibitor in potable water on mild steel corrosion. Corrosion measurements were done by weightloss and open circuit potential measurements. Optimum inhibitor concentration obtained for both corrosion rate and inhibition efficiency was 2g/100l. Adorption behaviour of Zingiber Officinale does not strictly follow Langmuir adsorption isotherm. Molecular interaction between the inhibitor molecules obey El Awady adsorption model. Adsorptions of pulverized Zingiber Officinale powder on mild steel coupons were further proved by its OCP values.
