@article { , title = {Nafion® Coated Electropolymerised Flavanone-based pH Sensor}, abstract = {This work summarizes the electrochemical response of flavanone carbon composite electrodes in comparison with Nafion®-coated flavanone carbon composite electrodes, for use as voltammetric pH sensors in both buffered and low-buffered media. Square wave voltammetric measurements suggest the peak potential achieved from the electrochemical polymerization after the electron-proton oxidation responds with accuracy to buffered pH solutions for both coated and non-coated electrodes, with a potential shift of 55.1 mV and 54.6 mV per pH unit respectively. However, a considerable improvement in stability, accuracy and sensitivity is provided by the proton-transfer Nafion® layer in CO2 bubbled sea water. Furthermore, Nafion®-coated flavanone carbon composite electrodes predicted a pH of 8.04 for the commercial seawater, which is in excellent agreement with the measured pH 8.05 value.}, doi = {10.1002/elan.202100652}, eissn = {1521-4109}, issn = {1040-0397}, journal = {Electroanalysis}, publicationstatus = {Published}, publisher = {Wiley}, url = {https://hull-repository.worktribe.com/output/3911193}, keyword = {pH, Electropolymerisation, Flavanone Square Wave, Voltammetry, Nafion}, author = {Miranda, Monica and Carvetta, Clara and Sisodia, Neel and Shirley, Luke and Day, Cristina and McGuinness, Kay and Wadhawan, Jay D. and Lawrence, Nathan S.} }
