“…Traditionally, the determination of iodine in salt (in the form of iodate) is performed by iodometric titration, however, it does not present the performance parameters documented in national and international publications, in order to contribute and support actions in health surveillance (Mello;Barbosa, 2015). The primary methodologies encountered in the literature regarding the detection and/or quantification of iodine in its various forms encompass a diverse range of techniques, including Brazilian Journal of Development, Curitiba, v.10, n.5, p. 01-18, 2024 spectrophotometry, chromatography, and electrochemical methods, among others (Fukushi, 2022;Galiga, 2021Galiga, , 2022Jamilan, 2019;Kulkarni, 2013;Pantůčková, 2004;Reddy-Noone, 2007;Silva, 1998;Wang, 2009;Xie, 2019). The selection of the most suitable method is contingent upon specific analytical requirements and the nature of the sample matrix.…”
