Study of thermodynamic features of an imidazoline inhibitor of the adsorption principle of action in hydrogen sulfide-containing environment
In continuation of the work in order to increase the effectiveness of nitrogen-containing corrosion inhibitors, the inhibitory properties, as well as the main kinetic and thermodynamic parameters of a modern imidazoline inhibitor in hydrogen sulfide-containing media, were studied. The effect of the inhibitory activity of the inhibitory composition in the process of corrosion protection of a metal surface was studied, depending on the concentration of the inhibitor (20-400 mg/l), temperature (20-70), exposure (24-720 h). Images of the metal surface in the process of corrosion, obtained using a scanning electron microscope, are presented. Based on the construction of Langmuir, Temkin, El-Awadi, and Freundlich adsorption isotherms of various models, the sorption mechanism is shown and the mechanism of action of this inhibitor is proposed. Corrosion inhibition proceeds by a mixed mechanism of physical and chemical adsorption, which is proved by experimentally obtained values of activation energy, enthalpy and entropy of activation, Gibbs energy, and the dependence of the sorption value on the equilibrium concentration of the inhibitor on the sorbent surface. The authors declare no conflicts of interests.
