| 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. |
