title: Determination of Iodide and Iodate by Ion Chromatography with Postcolumn Reaction and UV/Visible Detection.
abstract: Iodide and iodate can be determined by two new methods using anion-exchange chromatography with postcolumn reaction and UV/visible detection. Iodide is determined as IBr(2)(-) at 249 nm. Iodate is determined as I(3)(-) at 288 nm. The analyses can be run completely automatically and do not require any sample pretreatment. The detection limits for iodide and iodate are 0.1 μg/L. The methods have been successfully applied to determine iodide and iodate in several mineral waters and in drinking water as well as for the determination of iodide in table salt.
