摘要
提出石墨炉原子吸收光谱法测定钢中3种金属元素(As、Sn、Sb)的方法。该方法具有不用基体改进剂,分析灵敏度高的特点。另外该方法充分发挥了新型塞曼磁场扣背景的同一谱线,在不同的塞曼调制场合变化也不同的特点,提高了分析系统的抗干扰能力。
The paper presents the method for measuring 3 elements （As, Sn ＆ Sb） in steel using graphite oven atomic absorption spectrometry. This method characterizes that do not use matrix improver and possess high analysis sensitivity, moreover, fully applies the same spectral line of new Zeeman magnetic field and background, i.e. different change in different Zeeman mndulation condition, further increases the anti-interference capacity of analysis system.
