The data obtained are presented via dependences of the cathode ring current on the disk current ratio vs. the ring electrode potential. The analysis of the results was carried out by comparing the experimental polarization curves of the ring electrode with the data of cyclic voltammetry in model solutions to determine the electrical activities of various bromine compounds in positive oxidation states. We claim that the RRDE method could be used to obtain quantitative and qualitative data on the electrooxidation of bromide ions in neutral and alkaline solutions. For the most effective regeneration of the spent oxidizer, the values of pH &gt; 10 and moderate concentrations of NaBr should be used.<\/jats:p>","DOI":"10.3390\/membranes12090820","type":"journal-article","created":{"date-parts":[[2022,8,24]],"date-time":"2022-08-24T00:22:48Z","timestamp":1661300568000},"page":"820","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Analysis of the Composition of Bromide Anion Oxidation Products in Aqueous Solutions with Different pH via Rotating Ring-Disk Electrode Method"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7353-2938","authenticated-orcid":false,"given":"Roman","family":"Pichugov","sequence":"first","affiliation":[{"name":"EMCPS Department, Mendeleev University of Chemical Technology of Russia, 125047 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dmitry","family":"Konev","sequence":"additional","affiliation":[{"name":"Institute of Problems of Chemical Physics, Russian Academy of Sciences, 142432 Chernogolovka, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ivan","family":"Speshilov","sequence":"additional","affiliation":[{"name":"EMCPS Department, Mendeleev University of Chemical Technology of Russia, 125047 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lilia","family":"Abunaeva","sequence":"additional","affiliation":[{"name":"EMCPS Department, Mendeleev University of Chemical Technology of Russia, 125047 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0817-3331","authenticated-orcid":false,"given":"Mikhail","family":"Petrov","sequence":"additional","affiliation":[{"name":"EMCPS Department, Mendeleev University of Chemical Technology of Russia, 125047 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0720-4300","authenticated-orcid":false,"given":"Mikhail Alexeevich","family":"Vorotyntsev","sequence":"additional","affiliation":[{"name":"EMCPS Department, Mendeleev University of Chemical Technology of Russia, 125047 Moscow, Russia"},{"name":"Institute of Problems of Chemical Physics, Russian Academy of Sciences, 142432 Chernogolovka, Russia"},{"name":"Frumkin Institute of Physical Chemistry and Electrochemistry, Russian Academy of Sciences, 119071 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,8,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"596","DOI":"10.1002\/ente.201300108","article-title":"Optimization and analysis of high-power hydrogen\/bromine-flow batteries for grid-scale energy storage","volume":"1","author":"Cho","year":"2013","journal-title":"Energy Technol."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"199","DOI":"10.1016\/j.electacta.2017.03.132","article-title":"High performance redox flow batteries: An analysis of the upper performance limits of flow batteries using non-aqueous solvents","volume":"237","author":"Sun","year":"2017","journal-title":"Electrochim.
