| Abstract: | The air-acetylene flame atomic absorption spectrometry was used to determine Fe, Cu, Zn in the water and steam for thermal power station. The determination conditions of the various elements have been explored. The linear correlations of working curve were： Fe 0. 999 9,Cu 0.999 6,Zn 0. 999 5. The reclaimable rates of the method were：Fe 96.4%-104.8%, Cu95.5%-103.5%, Zn 101. 0%-105. 0%. |
