| 摘 要： | 建立了电感耦合等离子体质谱法测定磷矿石中碘的方法。试样经磷酸、高氯酸分解,用氨水调至弱碱性,直接用电感耦合等离子体质谱法测定,方法检出限为0.33μg/g,加标回收率为95.0%~97.4%,精密度(RSD,n=12)为2.77%~3.17%。经磷矿石国家一级标准物质(GBW 07210和GBW 07211)验证,结果满意。

| Abstract: | A method for the determination of iodine in phosphate ores by inductively coupled plasma mass spectrometry(ICP-MS) was developed.Sample was decomposed by H3PO4-HClO4 and sample solution was adjusted to weak alkaline using ammonia solution.Then the sample solution was directly determined by inductively coupled plasma mass spectrometry(ICP-MS).The detection limit of the method for iodine is 0.33 μg/g and the recoveries are 95.0%～97.4%.The method has been applied to the determination of iodine in National Standard Materials GBW 07210 and GBW 07211 and the results are in agreement with certified values with precision of 2.77%～3.17%RSD(n=12). |
