In situ monitoring of corrosion inhibitor film formation and efficiency using simultaneous dynamic EIS and microbalance measurement
Summary
Benzotriazole adsorption on nickel in hydrochloric acid was followed with simultaneous QCM and dynamic electrochemical impedance measurements. The inhibitor binds within seconds, its impedance signature tracks the mass change, and a correction for the dissolving metal gives adsorbed masses of about 0.3 to 0.5 µg/cm² for 1 to 10 mM benzotriazole.
