Abstract

Corrosion is an everyday challenge in all sectors of the economy particularly the manufacturing industry and this has led to massive economic loss. Literature is sparse on optimal Inhibition efficiency from Hydrochloric acid (HCl) and Tetra-oxo-sulphate (vi) Acid (H2SO4). The aim and objective of this research is to observe optimal Inhibition Efficiency from acidic media using cashew extracts as eco-friendly corrosion inhibitor. 0.1M of HCl and H2SO4 of 0.1M were used for the cashew extract in this research. Mild carbon steel with thickness 0.1 cm was used. It was cut into various coupons of dimensions 4 x 5 x 0.1 cm. The cashew waste extract produced was used as a corrosion inhibitor on mild carbon steel in 0.1M of HCl and H2SO4. It was observed that as the concentration of inhibitor increases, the inhibitor efficiency also increases. The optimal inhibition efficiency observed in HCl was 80.5% while 83.7% was in H2SO4. After 336 hours of test, it was concluded that H2SO4 is a better acidic medium.
