摘要：

The corrosion of the mild steel in 1 mol/L H2SO4 was investigated using Leucaena leucocephala pod extract(LLPE) as corrosion inhibitor by weight loss and electrochemical techniques.Inhibition efficiency of 95% was achieved with 500×10-6 of LLPE at 308 K.The polarization studies showed that LLPE acted as mixed type inhibitor.The adsorption of the studied inhibitor on mild steel obeyed Langmuir adsorption isotherm.Protective film formation against acid attack was confirmed by FT-IR,XRD and SEM techniques.
