高效液相色谱-电感耦合等离子体质谱法测定饮用水中碘酸根和碘离子
HPLC-ICP-MS Determination of Iodate and Iodide in Drinking Water
摘 要
提出了高效液相色谱-电感耦合等离子体质谱法测定饮用水中碘酸根和碘离子的方法。饮用水样品通过Dionex IonPac AS14阴离子交换柱及AG14保护柱分离碘酸根和碘离子,用50 mmol·L-1碳酸铵溶液(用氨水调至pH 9.9)作流动相进行淋洗。于洗脱液中用电感耦合等离子体质谱法分别测定碘酸根和碘离子的含量,两者的线性范围均为0.20~300 μg·L-1,检出限(3S/N)依次为0.09 μg·L-1和0.13 μg·L-1。以饮用水为基体加入两个不同浓度水平的标准溶液按方法分析后,求得方法的回收率及精密度为① 碘酸根回收率在100.5%~113.0%,相对标准偏差(n=8)在1.2%~2.8%之间;② 碘离子回收率在101.9%~110.7%,相对标准偏差(n=8)在1.3%~2.0%之间。

Abstract
A method of HPLC-ICP-MS for the determination of iodate and iodide in drinking water was proposed. Dionex IonPac AS14 anion chromagraphic column and AG14 guard column and 50 mmol·L-1 ammonium carbonate (adjusted to pH 9.9 with aq. ammonia) as mobile phase were used for separation of iodate and iodide. The eluates were used for ICP-MS determination, with linearity ranges between 0.20 to 300 μg·L-1 for both iodate and iodide. Values of detection limit (3S/N) found were 0.09 μg·L-1 for iodate and 0.13 μg·L-1 for iodide. Tests for recovery and precision were made by standard addition method at 2 different concentration levels, the results obtained were as follows: ① for iodate, recovery: 100.5% to 113.0%, RSD′s (n=8): 1.2% to 2.8%; ② for iodide, recovery: 101.9% to 110.7%, RSD′s (n=8): 1.3% to 2.0%.
