摘要
石煤矿试样经HNO3、HCl、HF和HClO4混酸[V(HNO3)∶V(HCl)∶V(HF)∶V(HClO4)=1∶3∶2∶3]溶解后,采用电感耦合等离子体原子发射光谱法测定试样中V、Mg、Zn、Fe、Cu、Mn含量。选择波长为210.230nm,285.213nm,213.856nm,259.940nm,327.396nm,257.610nm的谱线分别作为V、Mg、Zn、Fe、Cu、Mn的分析线,共存元素对测定没有影响,基体元素Si在溶样时以SiF4挥发而除去。在优化的实验条件下对石煤矿试样中上述元素进行测定,测定结果的相对标准偏差(RSD,n=5)在0.98%～2.1%范围,回收率在94%～102%之间。
The stone coal ore sample was dissolved in a mixed acid of HNO3, HCI, HF and HClO4 [V （HNO3） ： V （HCl） ： V（HF） ： V （HClO4）=1：3 ： 2 ： 3]. Then, the content of V, Mg, Zn, Fe, Cu and Mn in sample was determined by inductively coupled plasma atomic emission spectrometry （ICP-AES）. The wavelengths of 210. 230 nm, 285. 213 nm, 213. 856 nm, 259. 940 nm, 327. 396 nm and 257. 610 nm were used as the analytical lines for V, Mg, Zn, Fe, Cu and Mn. The coexisting elements did not have influence on the determination. The matrix Si was removed in form of SiF4 during sample dissolution. The elements above in stone coal ore sample were determined under the optimized conditions, with relative standard deviations （RSD, n=5） in range of 0.98 %-2.1 in the range of 94 %-102 %. , and recoveries
