| 摘 要： | 应用电感耦合等离子体质谱法测定饮用水中的硒元素。结果表明,高能碰撞模式(HEHe)较碰撞/反应池气体模式(He模式)消除干扰效果更好;在HEHe模式下,~(78)Se在0.5~100μg/L范围内线性良好,相关系数0.999 9,方法检出限为0.06μg/L,相对标准偏差为0.4%~0.8%,加标回收率为97.1%~103.2%。方法性能指标均能较好满足饮用水中Se的定量测试要求。

| Abstract: | Se in potable water was determined by ICP-MS.The results showed that high energy collision mode ( HEHe) was advanta-geous over collision/reaction cell gas mode (He) for eliminating interferences.In HEHe mode, the method had a good linearity for 78Se in the range of 0.5 ~100 μg/L, and the correlation coefficient (r) was over 0.999 9, and the method detection limit of 78Se was 0.06 μg/L.The relative standard deviations were between 0.4% and 0.8%, and the recoveries ranged from 97.1% to 103.2%.This method was suitable for quantitative determination of Se in potable water . |
