摘要:
为准确快速地检测铜尾矿中的铜铅锌银,选择电感耦合等离子体原子发射光谱仪( ICP-OES)对其进行测定, 对实验条件、方法检出限、精密度和加标回收率做了研究。 铜尾矿样品经氢氟酸-盐酸-硝酸分解后,用 ICP-OES 同时测定铜铅锌银 4 种元素,方法的检出限为 0.00062~ 0.0035 μg·mL-1 ,精密度为 0.67% ~ 3.08%,回收率为 90.0% ~ 110.0%。

Abstract：
In order to detect copper, lead, zinc and silver in copper tailings accurately and quickly, ICP-OES was selected. The experimental conditions, detection limit, precision and recovery of the method were studied. After the copper tailings sample was decomposed by hydrofluoric acid-hydrochloric acid-nitric acid, four elements of copper, lead, zinc and silver were determined simultaneously by ICP-OES. The detection limit of the method was 0.000 62~0.003 5 μg·mL-1 , the precision was 0. 67% ~3. 08%, and the recovery was 90. 0% ~110. 0%.
