dc.description.abstractIn recent years, polymeric surfactants have been investigated as efficient corrosion inhibitors for iron in acidic media. In this study, the inhibition performance of polyethylene glycol tert-octylphenyl ether (Triton X-114) for the corrosion of iron in 1M HCl solution has been evaluated. Potentiodynamic polarisation, electrochemical impedance spectroscopy, linear polarisation resistance techniques and long term experiments were used to achieve electrochemical studies. The effect of polyethylene glycol tert-octylphenyl ether on cathodic hydrogen evolution reaction was also investigated. The inhibition efficiency has increased with increasing inhibitor concentration. The standard free energy of adsorption (Delta G degrees(ads)) was calculated. The inhibitor adsorbed on the iron surface was found to be in a good agreement with the Langmuir adsorption isotherm. Polyethylene glycol tert-octylphenyl ether has improved the passivation characteristics of mild steel and inhibited the corrosion effectively in short time tests. The corrosion behaviour of mild steel was also supported by micrographing of the iron surfaces in 1M HCl solution with or without inhibitor.
