Spectrophotometric and ICP-MS methodology for iodine determination was compared. Samples were
alkali dry-ashed, dissolved in water, and iodine assayed by spectrophotometry and by ICP-MS. Iodine
content in the studied foods ranged from 3 to 1304 lg/100 g. There was no significant difference
(p > 0.05) between iodine values determined spectrophotometrically using an external calibration
curve and values determined using a standard addition.
