Resumo: The inhibition efficiency of sodium dodecyl sulfate (SDS) in controlling corrosion of carbon steel in aqueous solution containing 120 ppm of Cl− in the presence and absence of Zn2+ has been evaluated by weight loss method. The formulation consisting of 300 ppm of SDS and 75 ppm of Zn2+ gives 93 % inhibition efficiency. A synergistic effect exists between SDS and Zn2+. As the immersion period increases, the inhibition efficiency of SDS-Zn2+ decreases. Polarization study reveals that this formulation controls both the anodic and cathodic reactions. AC impedance spectra reveal that a protective film is formed on the metal surface.
