Abstract

The effect of inhibition and adsorption of waru leaf extract on corrosion of mild steel in hydrochloric acid solution was investigated. Weight loss, potentiodynamic polarization, Fourier transform infrared spectroscopy (FT-IR), and scanning electron microscopy (SEM) scans were used to assess the inhibiting properties of waru leaf extract in a solution of hydrochloric acid (HCl). The results showed that the rate of corrosion of mild steel in HCl solution sensitive the concentration of the extract as mass loss and the corrosion rates which decreases with increasing extract concentration and the corrosion rate increases with increasing temperature. The inhibition efficiency is above 80 % at room temperature with an increase in extract concentration and temperature. FTIR indicates that the inhibition is basically by application through the functional groups present in the extract while the energy of Langmuir adsorption activation and isotherm shows inhibition process. SEM images of the cores which were corroded showed holes as a corrosion mechanism reduced with the addition of extract. Overall, extract shows efficient use for inhibition of mild steel in HCl solution.
