| Abstract | ||
| Novel cationic surfactants were synthesized and evaluated as corrosion inhibitors for carbon steel in 1M HCl solution. The inhibition action of this surfactant was studied by weight loss and galvanostatic polarization methods. The structure of the prepared compounds was established by spectral tools (FT-IR and 1H-NMR). Also, CMC and anti-microbial activity were evaluated. The adsorption of the inhibitors was described by Langmuir adsorption isothermal. The inhibition efficiency increases by increasing surfactant concentration and decreasing temperature. Where, the prepared compound S at concentration 5 x 10-4mol/l at 20 recorded 94.45 %.The effect of temperature on the inhibition efficiency of corrosion process was studied. Also, thermodynamic parameters were calculated to predict the reliable mechanism of inhibition | ||
