英文摘要	In this work, a method was developed to separate and determine IO3- and I(-)by high performance liquid chromatography coupled with inductively coupled plasma mass spectrometry. ICS-A23 ion chromatography column and its guard column ICS-A2G were selected, mobile phase of the HPLC was (NH4)(2)CO3 of 0. 03 mol/L at flow rate of 1 mL/min. The detection limits of 0. 035 mu g/L for 103 and 0. 025 mu g/L for I- were obtained when the Shield Torch high sensitivity mode of ICP-MS and 1000 mu L injection volume of HPLC were applied. The detection limits can satisfy the quantified detection of the iodine speciation in the ground water. The sensitivity difference between iodate and iodide was observed by HPLC-ICP-MS system. Aslo, this problem was soluved by changing the storing medium of the standard solution. The IO3- to I- peak area ratios by HPLC-ICP-MS measurement were still near to 1 1 when the mix standard solution had been stored in the 0. 01% KOH medium for 5 days.
