| 摘 要： | 火焰原子吸收法（即ＡＡＳ法）测量钢样中铬、镍、铜、锰的含量，由于基体中大量存在铁元素的干扰．影响结果的准确性。本文以大量的实验结果为依据，提出选择适当吸收波长并加入氯化铵干扰抑制剂，可以达到较高的准确度和精密度。从而使ＡＡＳ法连续测定钢样中的铬、镍、铜、锰成为一种简捷、快速、稳定、有效的分析方法。

| Abstract: | In the determination of Cr, Ni, Cu and Mn in alloy steel samples by flame AAS,the precise results are difficult to obtain because of the matrix-element Fe interference. Based on a lot of experimental data,it is found that the high accuracy and precision of the results can be obtained by selecting proper resonance lines and adding ammonium chloride of interferential inhibitor.And the continuous determination of Cr, Ni, Cu and Mn in steel samples by AAS becomes simple, fast, stable and effective. |
