| 摘 要： | 采用火焰原子荧光法（FAFS）和电感耦合等离子体质谱法（ICP-MS）测定铅锌矿中的镉. 通过对比研究，两种方法的校准曲线相关系数良好（r>0.999 5），方法检出限、准确度和精密度均符合质量规范要求. 经过铅锌矿实际样品的比对，两种方法不存在显著性差异. FAFS法比ICP-MS法测定时间短，精密度高，适用于大批量铅锌矿样品的测定.

| Abstract: | The flame atomic fluorescence spectrometry (FAFS) and inductively coupled plasma mass spectrometry (ICP-MS) were used to determine cadmium in lead-zinc ores. Through comparative study, the correlation coefficients of calibration curves of the two methods were good (r>0.999 5), and the limit of detection, accuracy, and precision of the methods met the requirements of the quality specifications. After comparing the actual samples of lead-zinc ores, there were no significant difference between the two methods. Compared to ICP-MS, the FAFS has shorter measurement time and higher precision, making it suitable for the determination of large quantities of lead-zinc ore samples. |
