Abstract
Assessment of the corrosion inhibition behaviour of Sodom apple (calotropis procera) latex extract for the prevention of corrosion on mild steel using gravitation method was conducted in this research. The latex was extracted and Phytochemical analysis of the extract was conducted. The presence of saponins, alkaloids, terpenes, flavonoids, glycosides, reducing sugars and tannins were tested for by the simple qualitative and quantitative methods. Corrosion test was carryout using 16 mild steel sheet coupons in 0.5 M H2SO4 acidic medium with and without addition of the plant extract (inhibitors). The corrosion inhibition behaviour of the latex test using gravitational method and the result revealed that latex is effective in inhibiting corrosion. The analysis showed that the inhibition efficiency of the inhibitor increased with the increase of plant extract concentration but mildly reduces with increase in exposure time. It is recommended that further work should be carried on the corrosion inhibition efficiency of Sodom apple (calotropis procera) latex in alloys and other corrosive mediums. The effect of increasing the inhibitor concentration beyond 2.5ml should be looked into. Also, the storage stability, durability and industrial applicability of the Sodom apple (calotropis procera) latex need to be explored.
