摘要
粗锌试料采用盐酸过氧化氢分解,在盐酸介质中,使用空气-乙炔火焰,于原子吸收光谱仪波长248.3 nm处,测定铁的吸光度。此方法准确可靠、灵敏度高、干扰少、重现性好、已用于实际样品的分析检测,结果准确稳定,对实际分析工作有指导作用。
The crude zinc sample was dissolved by HCI-H2 02 with low temperature heating, analyzed by flame atomic absorption spectrometry under the most sensitive absorbing line for determination of iron - 248.3 nm. The method in this paper is simple, rapid and has wide linear range. The results of analysis are accurate and stable, which has the instruction function to the actual analysis work.
