The environmental concern relates mostly to the formation of carbon disulfide (CS<jats:sub>2<\/jats:sub>) and the heavy metal complexes of xanthates. Due to the unstable nature and multiple reaction mechanisms of xanthates, their reliable determination at low concentration levels is difficult. In this study, a xanthate pretreatment method was optimized and applied for the determination of ethyl xanthate (EX<jats:sup>\u2212<\/jats:sup>) by high performance liquid chromatography\u2013inductively coupled plasma tandem mass spectrometry (HPLC\u2013ICP-MS\/MS). Ethyl xanthate was oxidized to diethyl dixanthogen ((EX)<jats:sub>2<\/jats:sub>) by triiodide (I<jats:sub>3<\/jats:sub>\n                  <jats:sup>\u2212<\/jats:sup>) in aqueous solution and the formed (EX)<jats:sub>2<\/jats:sub> was extracted into n-hexane. Important experimental parameters, including pH, I<jats:sub>3<\/jats:sub>\n                  <jats:sup>\u2212<\/jats:sup> amount, and oxidation time, were optimized and the detection limit of 0.29\u00a0mg\u00a0L<jats:sup>\u22121<\/jats:sup> for potassium ethyl xanthate was obtained. During the optimization experiments, it was found that the oxidation reaction resulted in multiple products, decreasing the efficiency of (EX)<jats:sub>2<\/jats:sub> formation and, therefore, the sensitivity of the method. The proposed method was applied to wastewater samples with recoveries of 105\u2013106%. This study provides a selective method for the determination of ethyl xanthate and introduces novel information on the parameters affecting the oxidation of xanthates.<\/jats:p>\n               <jats:p>\n                  <jats:bold>Graphical abstract<\/jats:bold>\n               <\/jats:p>","DOI":"10.1007\/s44211-022-00155-x","type":"journal-article","created":{"date-parts":[[2022,7,7]],"date-time":"2022-07-07T13:33:04Z","timestamp":1657200784000},"page":"1221-1231","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["The effect of experimental conditions on the formation of dixanthogen by triiodide oxidation in the determination of ethyl xanthate by HPLC\u2013ICP-MS\/MS"],"prefix":"10.1007","volume":"38","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4775-980X","authenticated-orcid":false,"given":"Ronja","family":"Suvela","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Simon","family":"Genevrais","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matti","family":"Niemel\u00e4","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7106-5678","authenticated-orcid":false,"given":"Paavo","family":"Per\u00e4m\u00e4ki","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2022,7,7]]},"reference":[{"key":"155_CR1","doi-asserted-by":"publisher","first-page":"265","DOI":"10.1016\/B978-0-08-097053-0.00012-1","volume-title":"Wills\u2019 Mineral Processing Technology","author":"BA Wills","year":"2016","unstructured":"B.A. Wills, T.
