The detection of the above analyte was based on the electrogeneration of iodine from iodide on a boron-doped diamond electrode, without modifications, in the presence of 0.1 mol dm\u22123 HClO4 as a supporting electrolyte. The electrogenerated iodine reacted with sulfur dioxide, forming iodide ions and sulfuric acid (i.e., a Bunsen reaction). The product of this reaction, the iodide ion, diffused back to the surface of the boron-doped diamond electrode and oxidized itself again. This chemical redox cycling enhanced the voltammetric response of the boron-doped diamond electrode. The selectivity of the determination was assured using NaOH and formaldehyde during sample preparation, and a blank was also measured and taken into account. The detection limit was estimated to be 10\u22126\u201310\u22127 mol dm\u22123. However, the content of sulfur dioxide in wine is significantly higher, which can lead to more accurate and reliable results.<\/jats:p>","DOI":"10.3390\/ijms241612875","type":"journal-article","created":{"date-parts":[[2023,8,17]],"date-time":"2023-08-17T10:15:48Z","timestamp":1692267348000},"page":"12875","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["An Interference-Free Voltammetric Method for the Detection of Sulfur Dioxide in Wine Based on a Boron-Doped Diamond Electrode and Reaction Electrochemistry"],"prefix":"10.3390","volume":"24","author":[{"given":"Eva","family":"Culkov\u00e1","sequence":"first","affiliation":[{"name":"Electroanalytical Chemistry Laboratory, Department of Chemistry and Physics, Faculty of Education, Catholic University in Ru\u017eomberok, Hrabovsk\u00e1 Cesta 1, SK-034 01 Ru\u017eomberok, Slovakia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zuzana","family":"Luk\u00e1\u010dov\u00e1-Chomistekov\u00e1","sequence":"additional","affiliation":[{"name":"Electroanalytical Chemistry Laboratory, Department of Chemistry and Physics, Faculty of Education, Catholic University in Ru\u017eomberok, Hrabovsk\u00e1 Cesta 1, SK-034 01 Ru\u017eomberok, Slovakia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Renata","family":"Bellov\u00e1","sequence":"additional","affiliation":[{"name":"Electroanalytical Chemistry Laboratory, Department of Chemistry and Physics, Faculty of Education, Catholic University in Ru\u017eomberok, Hrabovsk\u00e1 Cesta 1, SK-034 01 Ru\u017eomberok, Slovakia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Miroslav","family":"Rievaj","sequence":"additional","affiliation":[{"name":"Electroanalytical Chemistry Laboratory, Department of Chemistry and Physics, Faculty of Education, Catholic University in Ru\u017eomberok, Hrabovsk\u00e1 Cesta 1, SK-034 01 Ru\u017eomberok, Slovakia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jarmila","family":"\u0160vancarov\u00e1-La\u0161tincov\u00e1","sequence":"additional","affiliation":[{"name":"Central Controlling & Testing Institute for Agriculture in Bratislava, Mat\u00fa\u0161kova 21, SK-833 16 Bratislava, Slovakia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peter","family":"Tom\u010d\u00edk","sequence":"additional","affiliation":[{"name":"Electroanalytical Chemistry Laboratory, Department of Chemistry and Physics, Faculty of Education, Catholic University in Ru\u017eomberok, Hrabovsk\u00e1 Cesta 1, SK-034 01 Ru\u017eomberok, Slovakia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,8,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Pozo-Antonio, J.S., Rivas, T., Dion\u00edso, A., Barral, D., and Cardell, C.
