The inhibition effect of lignin sulfonate against corrosion for mild steel in acidic solution has been examined by means of FTIR (fourier transform infrared spectroscopy), FAA (flame atomic absorption) spectroscopy, SEM (scanning electron microscope), EDS (energy dispersive X-ray spectroscopy), and mass loss techniques. The results revealed that lignin is a beneficial inhibitor for mild steel corrosion in acidic medium. It has been further found that Langmuir adsorption isotherm is obeyed by the tested lignin's adsorption over the surface of mild steel. The range of inhibition efficiency (IE) in 2 mol · L−1 HCl was found to be 75.88 % − 87.88% for Reax 88A, 10.72% − 60.32% for Reax 88B, and 51.32% − 63.03% for Reax 100M, after immersed at 298 K for 24 h time.
