Abstract:

The adsorption behavior of thiazole inhibitior on the surface of N80 carbon steel was studied by potentiodynamic polarization curves in heterogeneous NaCl solution at pH=4. The electrochemical parameters were fitted. The result shows that thiazole inhibitor is of anodic adsorption, and the inhibition efficiency increases with the concentration increasing (4.9×10^-4~1.9×10^-3mol/L), but decreases with the temperature increasing (30~60°C). The thermodynamics of this adsorption was also discussed. The result is shown that the adsorption is according with Langmuir adsorption isotherm formula in acidic condition, and adsorption is a spontaneous behavior.
