摘要
试料经熔融法处理,于波长197.313 nm处用ICP-AES测定铼量。实验表明,方法的相对标准偏差为0.42%-2.61%,样品加标回收率为95.7%-101.9%。方法灵敏度高、结果准确、操作简便,适合铜砷滤饼中的铼含量0.005 0%-2.500 0%的测定。
The sample was processed by the melting method,and the amount of rhenium was measured by ICP-AES at a wavelength of 197.313 nm.The results show that the relative standard deviation of the method is 0.42%~2.61%,and the sample recovery rate is 95.7%~101.9%.The method has high sensitivity,accurate results,and simple operation.It is suitable for the determination of 0.0050%~2.5000%rhenium in copper-arsenic filter cake.
