Determination of iodide and iodate by ion chromatography with postcolumn reaction and UV/visible detection

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 IBr2- at 249 mn. 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 mu g/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.
