Abstract

The inhibitive effect of Musa acuminata Red Dacca flower extract in 1N HCl / H2SO4 acid on mild steel was calculated using weight loss method and surface examination study by FTIR. The extract of the Red Dacca flower extract was subjected to preliminary phytochemical screening to identify the chemical constituents of the plant. The results revealed strong presence of tannins and steroids and moderate presence of, alkaloids, terpenoids, reducing sugar and coumarins. The corrosion inhibition efficiency studied showed that the inhibition efficiency increased with increase in the concentration of the extract. RD flower extract showed a maximum efficiency of 99.40% and 96.99% at 2.5 % v/v in 1N HCl and 1N H2SO4 respectively.
