| 中文摘要: |
| 选取346.046 nm作为铼元素的测试谱线，建立了电感耦合等离子体发射光谱法(ICP-OES)测定金饰品中铼元素含量的方法。在0~5.0 μg/mL线性范围内，标准曲线相关系数0.9984，检出限为0.0224 μg/mL。加标量为1.0, 3.0, 5.0 μg/mL时，相对标准偏差(RSD，n =6)分别为0.64%，0.55%，0.78%，平均加标回收率分别为102.7%，97.7%，93.7%。结果表明，该方法适用于金饰品中铼元素的测定。 |

| An inductively coupled plasma optical emission spectrometry (ICP-OES) method based on the determination of rhenium in gold adornment was established, 346.046 nm was selected as the test spectral line of rhenium. In the linear range of 0~5.0 μg/mL, the correlation coefficient of the standard curve was 0.9984, and the detection limit was 0.0224 μg/mL. Under the three spiked levels of 1.0, 3.0 and 5.0 μg/mL, the relative standard deviations (RSD, n= 6) were 0.64%, 0.55% and 0.78%, the recovery rate were 102.7%, 97.7% and 93.7%, respectively. The results showed that this method was suitable for the determination of rhenium in gold adornment. |
