Dissolved Oxygen and pH Microelectrode Measurements at Water-Immersed Metal Surfaces
Abstract
Investigation of microbial corrosion requires incorporation of both electrochemical and microbiological methods. Dissolved oxygen (DO) and pH were measured at metal/artificial seawater interfaces using microelectrodes in biotic and abiotic system. Measurements in a closed system proved that presence of electrochemical and/or biological reaction products substantially influence the conditions at the metal surface. For long-term studies, only open (e.g., continuous flow) reactors should be used. An open channel flow reactor suitable both for microbiological and electrochemical measurements has been constructed and successfully tested. Reprints.
