Abstract The inhibition effect of exopolysaccharide (EPS) extracted from Vibrio neocaledonicus sp. on carbon steel Q235 has been studied by means of potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and scanning electronic microscopy (SEM). The results showed that EPS could inhibit effectively the corrosion for Q235 steel in solution of 0.5 mol/L H2SO4 because of that a film of Fe-EPS could formed on carbon steel during the corrosion process. The inhibition efficiency reached the maximum when the concentration of EPS was 1.0 g/L. The absorption of EPS on Q235 steel was chemisorption and obeyed the Langmuir adsorption isotherm. The composition of EPS was identified by using FTIR.
