Using flame atomic absorption spectrometric method to detect magnesium contented in aluminum and aluminum alloy

QAIO Jun1,HU Yalun2(1. Dalian Inst. of Product Quality Supervision and Inspection, Dalian 116021, China;2. Dalian professional and Technological College, Dalian 116031, China)  
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%.
