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>0.9995),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.
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>0.9995),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.
