火焰原子吸收光谱法快速测定铁矿石中铅锌铜

Rapid Determination of Lead, Zinc and Copper in Iron Ores by Flame Atomic Absorption Spectrometry

摘要: 将ISO、国家标准等方法中同一铁矿石样品分别称样，用不同的方法溶样，再分别测定改进为对同一样品一次称样，盐酸、氢氟酸一次性溶样，应用空气-乙炔火焰原子吸收光谱法连续测定同一进口铁矿石中铅、锌和铜含量，可简化操作，减少误差。方法准确、可靠，提高了工作效率和经济效益。

Abstract: In both international and national standard methods for the determination of Pb, Zn and Cu in iron ore samples, the different sample digestion procedures should be used for different element determination, which was not only timeconsuming but also increasing the contamination risks and costs. Therefore, an improved method was developed, in which sample was pretreated with HClHF mixed acid only once and then the three elements of Pb, Zn and Cu in sample solution were determined by airacetylene flameatomic absorption spectrometry. The improved method provides the advantages of simple operation, accuracy, crediblity and efficiency. The method has been applied to the determination of Pb, Zn and Cu in imported iron ores.
