| 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78Se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: |
| e in potable water was determined by ICP MS. The results showed that high energy collision mode（HEHe） was advantageous over collision/reaction cell gas mode （He） for eliminating interferences. In HEHe mode， the method had a good linearity for78Se in the range of 0.5 ~ 100 μg/L， and the correlation coefficient（r） was over 0.999 9， and the method detection limit of78Se 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. |
