Development of dynamic method for evaluation of inhibition efficiency on the example of 8-hydroxyquinolin
Selection of a proper inhibitor should be based on the evaluation of its mechanism and effective concentrations. Mechanism of inhibition usually has dynamic character due to changing physicochemical conditions of the environment and corroding metal surface. Most of actually used methods are stationary or contain assumptions which highly influences obtained values. Development of new dynamic method, based on modified EIS, allows excitation of the system by signal composed of galvanodynamic perturbation and AC signal as a set of 20 sinusoids. Such an approach allowed comparison of the obtained results by two simultaneous methods and verification of the selected electric equivalent circuit. Instant value of charge transfer resistance of mild steel exposed to industrial water with changing concentration of 8-Hydroxyquinoline in the system was determined.
