摘要
建立了铅试金富集—微波消解—电感耦合等离子体原子发射光谱仪测定合质金中铱的分析方法,确定了样品溶解方法和测试条件。该方法精密度和准确度的验证实验结果表明,测定铱的相对标准偏差(RSD)小于4.90%,加入标准物质回收率为97.44%～99.62%,分析结果准确可靠。
The paper established a determination method of Ir in alloy gold by lead assay enrichment- mircowave digestion- ICP- AES and settled sample dissolution method and test conditions. The precision and accuracy verification results show that RSD is kept below 4. 90 % and the recovery rate with addition of standard substance is between97. 44 % and 99. 62 %.
