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0~5.0μg/mL线性范围内,标准曲线相关系数0.9984,检出限为0.0224μg/mL。加标量为1.0,3.0,5.0μg/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 0~5.0μg/mL,the correlation coefficient of the standard curve was 0.9984,and the detection limit was 0.0224μg/mL.Under the three spiked levels of 1.0,3.0 and 5.0μg/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.
