Abstract.
The cassava leaves were successfully collected and 60g of different extracts of Manihot esculenta was
obtained using standard laboratory procedures. Volumetric concentrations of the leaves extracts
3 expressed in cubic centimeter (cm ) were determined and the concentrations of the acid, alkali and salt for different moles were also determined. The weight loss of each of the sample coupons of mild steel were determined and recorded. The composition of the mild steel rods was analyzed using Optical Emission Spectrometer. From the result obtained it can be suggested that the Manihot Esculenta leaf extracts act as good green corrosion inhibitor and can be used to retards the corrosion rate on mild steel.
Key words: cassava leaf, mild steel, corrosion.
