摘要: 采用盐酸-氢氟酸体系溶解铁矿石,分别采用火焰吸收法(加氯化铯)、火焰吸收法(不加氯化铯)和火焰发射法(不加氯化铯)测定其中氧化钠和氧化钾的含量并进行了比较。结果表明,发现对于测定铁矿石中的氧化钠、氧化钾来说,以上3种方法测定出的结果都是可以采纳的,并对此结果进行了初步分析。

Abstract: Iron ores were dissolved with HCL+HF and their Na2O and K2O contents were measured by methods of flame absorption (adding CsCL), flame absorption (not adding CsCL) and flame emission (not adding CsCL). Comparison is made between them and shows that the measurement results obtained by the three methods are all acceptable, which are preliminarily analyzed.

Key words: Flame emission, Flame absorption, CsCL, Iron ore, Na2O, K2O
