Sophisticated Electrochemical methods for MIC investigation and monitoring

Abstract

AbstractDue to the electrochemical nature of MIC electrochemical methods are useful tools to study reactions at the metal/biofilm interface, investigate MIC mechanisms and monitor the onset of MIC and its propagation. The paper discusses various electrochemical methods—measurement of corrosion potential, redox potential, polarization resistance, galvanic currents, large signal polarization techniques, random potential pulse method, electrochemical impedance spectrometry, electrochemical relaxation methods (programmed pulse relaxation, sinusoidal ac relaxation), electrochemical noise analysis, scanning vibrating electrode techniques (Kelvin probe, vibrating microreference electrode, electrochemical sensors)–;with respect to their applicability and merits for MIC investigations and monitoring.
