The possibility of the separation of speciations of tin using liquid\u2013liquid extraction (LLE); precipitation with fluorides, iodides, ammonia, and iron (III) chloride; and sorption of organotin compounds (OTCs) was studied. The LLE and analyte precipitation methods proved to be ineffective. Inorganic and organic forms of tin were separated by the sorption of OTCs using silica gel sorbent Diapak C18. Under optimized conditions, a technique for the separate determination of the forms of tin in natural waters was developed. The technique combines hydride generation and microwave mineralization of solutions followed by ICP spectrometry. The inorganic forms of tin were determined after their solid-phase separation from organotin compounds. The lower limits of analyte quantification were 0.03 \u03bcg\/L (ICP-MS) and 0.05 \u03bcg\/L (ICP-OES), which provide separate determinations of inorganic and organic forms of tin in waters with different salinities. The content of OTCs in water was determined by subtracting the inorganic concentration from the total concentration of tin. The technique will allow a comprehensive assessment of the toxicological impact of tin speciations on the aquatic ecosystem.<\/jats:p>","DOI":"10.3390\/molecules28186615","type":"journal-article","created":{"date-parts":[[2023,9,14]],"date-time":"2023-09-14T10:09:22Z","timestamp":1694686162000},"page":"6615","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Possibilities and Limitations of ICP-Spectrometric Determination of the Total Content of Tin and Its Inorganic and Organic Speciations in Waters with Different Salinity Levels\u2014Part 2: Separate Determination of Inorganic and Organic Speciations of Tin"],"prefix":"10.3390","volume":"28","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5284-0317","authenticated-orcid":false,"given":"Zaual","family":"Temerdashev","sequence":"first","affiliation":[{"name":"Analytical Chemistry Department, Faculty of Chemistry and High Technologies, Kuban State University, 350040 Krasnodar, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pavel","family":"Abakumov","sequence":"additional","affiliation":[{"name":"Analytical Chemistry Department, Faculty of Chemistry and High Technologies, Kuban State University, 350040 Krasnodar, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2506-8629","authenticated-orcid":false,"given":"Mikhail","family":"Bolshov","sequence":"additional","affiliation":[{"name":"Institute for Spectroscopy Russian Academy of Sciences, 108840 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Darya","family":"Abakumova","sequence":"additional","affiliation":[{"name":"Analytical Chemistry Department, Faculty of Chemistry and High Technologies, Kuban State University, 350040 Krasnodar, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2484-5377","authenticated-orcid":false,"given":"Alexander","family":"Pupyshev","sequence":"additional","affiliation":[{"name":"Department of Physical and Chemical Methods of Analysis, Institute of Physics and Technology, Ural Federal University, 620062 Yekaterinburg, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,9,14]]},"reference":[{"key":"ref_1","unstructured":"Cima, F.
