摘要
前人利用有机显色剂测定铸铁及铝合金中含镁量。报道了火焰原子吸收光谱法测定纯铝及铝合金中镁含量。试样采用盐酸、硝酸溶解,再加入抑制剂氯化锶。在波长285.2nm处测定吸光度,从而确定镁含量。测定范围为0.020%～0.50%。
The method of color displaying by organic agent is generally employed to detect magnesium contents in iron and aluminum alloy. This paper reports the flame atomic absorption spectrometric method used for detecting magnesium contents in aluminum or aluminum alloy. Samples are dissolved in hydrochloric acid and nitric acid, before addition strontium chloride. Magnesium content is determined via measuring the absorbency at wavelength 285.2nm, with detection precision in the range of 0.020%-0.50%.
