| Abstract: | The effect of H2S on the inhibition action of propargyl alcohol(PA) in Fe/H2SO4 system has been investigated by electrochemical potentiodynamic and potentiostatic methods. The results showed that PA could inhibit the anodic and cathodic reactions of iron corrosion effectively in H2SO4 solution containing H2S. At low content of PA the inhibition efficiency decreased with the increase of H2S content due to the strong interaction of H2S and HS- with Fe. At high content of PA, Fe(HS-)ads is stabilized owing to the hydrogen bonds and electrostatic action, which made the anodic current approach to zero. The interaction between PA and Fe(H2S)ads in this case is weak. |
