Novel Electrochemical Detections Of Biologically And Environmentally Relevant Substances, Clarissa E. Tatum
Novel Electrochemical Detections Of Biologically And Environmentally Relevant Substances, Clarissa E. Tatum
Doctoral Dissertations
Development and studies of new electrochemical methods for the detection of various biologically and environmentally relevant substances are the focus of this dissertation. A dual amperometric sensor, capable of the simultaneous, real-time determination of NO and O,2, has been developed and optimized. Many tests were performed in order to reduce cross-talking between the two sensors, and an electro-deposited polymer, poly-5-amino-1-naphthol, was shown to reduce the cross-talking to insignificant levels. The use of bismuth-based electrodes in the detection of various metals has been explored. A bismuth bulk electrode has been developed, optimized, and used for the individual and simultaneous determination of …
