| 中文摘要: |
| 建立了一种王水溶样后直接采用电感耦合等离子体发射光谱仪同时测定金镍合金中铝、铋、镉、钴、铬、铜、铁、镁、锰、钼、铅、锑、锡、钛和锌等15种杂质元素的方法。对各杂质元素的分析谱线和基体干扰进行了研究，采用扣除背景的方法校正基体中金和镍的影响。该方法的检出限为0.00036~0.036 μg/mL，测定范围为0.001%~0.1%。加标回收率为89.1%~108.3%，相对标准偏差(RSD)为0.79%~3.54%。方法可满足实际样品分析要求。 |
| 英文摘要: |
| A method for the simultaneous determination of 15 impurity elements in gold nickel alloy, such as aluminum, bismuth, cadmium, cobalt, chromium, copper, iron, magnesium, manganese, molybdenum, lead, antimony, tin, titanium and zinc, was established by inductively coupled plasma atomic emission spectrum (ICP-AES). The influence of gold and nickel in the matrix was corrected by background subtraction. The detection limit of this method is 0.00036~0.036 μg/mL, and the detection range is 0.001% ~0.1%. The recovery was 89.1% ~108.3%, and the RSD was 0.79% ~3.54%. The method can meet the requirements of practical sample analysis. |
