Synergism between N; N-dimethyl-2-(phenyl (o-tolyl)methoxy)ethanamine and iodide ions on the Corrosion of Carbon Steel in 1 M HCl

Ahmed A. Farag [7] | I. M. Ibrahim [2]


Abstract: Corrosion inhibition of carbon steel in 1 M HCl by N; N-dimethyl-2- (phenyl (o-tolyl) methoxy) ethanamine (DPTA) ; in the absence and presence of iodide ions was investigated using weight loss; potentiodynamic polarization and electrochemical impedance spectroscopy techniques. The results revealed that DPTA inhibit the steel corrosion and the inhibition increases by increasing its concentration and increases further by the addition of iodide ions. The adsorption of DPTA on the carbon steel surface was found to obey Langmuir adsorption isotherm. Synergism parameters (S) are more than unity indicates that the enhanced inhibition efficiency in the presence of iodide ions is only due to synergism.
