火焰原子吸收光谱法定量测定铁矿石中的Cu、Pb、Zn

Determination of Cu,Pb,Zn in Iron Ore with Flame Atomic Absorption Spectrometry

试样经盐酸-硝酸-氢氟酸-高氯酸四酸溶解,盐酸复溶作介质,用火焰原子吸收光谱法连续测定矿石中Cu、Pb、Zn三种元素,研究了基体干扰及消除方法,对铁矿石标准物质进行测定,测定值与认定值一致,符合检测方法要求。

The samples of copper, lead and zincin ore were dissolved with a four-acid system of HCl-HNO3-HF-HClO4, and made the determination by Flame Atomic Absorption Spectrometry （FAAS） in hydrochloric acid medium. The interference of matrix and its elimination way were studied. For determination of iron ore certifide reference materials, the results were consistent with the certified values, which met the requirements for detection method.
