SOPHISTICATED ELECTROCHEMICAL METHODS FOR MIC INVESTIGATION AND MONITORING

Due to the electrochemical nature of MIC electrochemical methods are u seful tools to study reactions at the metal/biofilm interface, investi gate MIC mechanisms and monitor the onset of MIC and its propagation T he paper discusses various electrochemical methods - measurement of co rrosion potential, redox potential, polarization resistance, galvanic currents. large signal polarization techniques, random potential pulse method, electrochemical impedance spectrometry, electrochemical relax ation methods (programmed pulse relaxation, sinusoidal ac relaxation), electrochemical noise analysis, scanning vibrating electrode techniqu es (Kelvin probe, vibrating microreference electrode, electrochemical sensors) - with respect to their applicability and merits for MIC inve stigations and. monitoring.
