Summary on Grant Application Form
Historically the focus of impedance process tomography has been towards industrial application involving relatively passive materials that exhibit distinctive impedance signatures. However, as this technology progresses into the chemical production arena the issues associated with electrochemical reactions at the sensing electrodes must also be considered. These reaction mechanisms can lead to contamination or breakdown of high value products as well as degrade the tomographic signals leading to sub optimal imaging. This proposal is aimed at investigating electrochemical processes for specific target materials using cyclic voltammetry and impedance spectroscopy to probe the electrode/solution interface. Cyclic voltammetry will provide information on oxidation/reduction processes and excitation potentials at which these reaction will take place. Impedance spectroscopy will allow the reaction mechanisms to be investigated further and has the potential to resolve both the interface impedance and the bulk impedance of the system. The investigation will exploit the unique features of microelectrode electrochemical sensors and in particular their ability to establish a steady state diffusion limited current. This is a particularly useful when the bulk impedance is changing due to the filtration process. Unlike conventional large sized electrodes microelectrode sensors are also capable of being used in resistive media without added supporting electrolyte and are therefore ideally suited to this application.
