石煤酸浸渣试样经灼烧后用混酸(HN03、HCl、HF和HClO_4)溶解,采用电感耦合等离子体原子发射光谱法测定试样中8元素的含量。选择波长为309.31lnm、259.94nm、259.373nm、184.006nm、280.27nm、237.312nm、766.49nm和589.59nm的谱线分别为钒、铁、锰、钙、镁、铝、钾、钠等的分析线。该法操作简单,分析快速、可靠。该方法已经成功应用于对石煤酸浸渣试样中上述元素进行测定.8种待测元素测定结果的相对标准偏差(RSD:12)均小于5%,加标回收率在96~103%之间。
After being burned, the sample of the stone acid leachate was dissolved with mixed acid (HN03, HCl, HF and HClO_4), and the content of 8 elements in the sample was determined by inductively coupled plasma atomic emission spectrometry. The spectral lines of the selected wavelengths of 309.31lnm, 259.94nm, 259.373nm, 184.006nm, 280.27nm, 237.312nm, 766.49nm and 589.59nm are the analytical lines of vanadium, iron, manganese, calcium, magnesium, aluminum, potassium, sodium and the like . The method is simple, fast and reliable analysis. The method has been successfully applied to the determination of the above elements in the samples of the stone-leachate samples.The relative standard deviations (RSDs) of the eight kinds of elements to be measured are less than 5%, and the recoveries of spiked samples are 96-103% between.
