| 摘 要： | 提出了一种快速测定镍铜合金中的锰和铁的电感耦合等离子体原子发射光谱法(ICP-AES)。样品用硝酸溶解, 选择257.610 nm 和259.940 nm波长的谱线分别作为锰和铁的分析线, 运用基体匹配的校准曲线, 在优化仪器工作参数条件下测定, 基体和共存元素对测定没有干扰, 方法的检出限分别为0.001%(锰)和0.000 6%(铁)。方法用于镍铜合金标准样品中锰和铁的测定, 测定值与认定值一致, 相对标准偏差为1.0%(锰)和0.88%(铁)。

| Abstract: | A rapid method was proposed for determining Mn and Fe in nickel-copper alloy by inductively coupled plasma atomic emission spectrometry(ICP-AES) after the dissolution of sample with nitric acid. By selecting 259.940 nm and 257.610 nm as Fe and Mn analytical lines respectively and using calibration curve after matrix matching, the matrix and coexisting elements showed no interference under optimized instrument working parameters. The detection limits of the method were 0.006 % for Mn, and 0.0001 % for Fe. In determining Mn and Fe in nickel-copper alloy by this method, the results were consistent with the certified values. The relative standard deviations (RSDs) were 1.0 % for Mn and 0.88 % for Fe. |
