火焰原子吸收光谱法测定高铝锌基合金中的镁

Determination of Magnesium in High-Aluminium Zinc-Base Alloy by Flame Atomic Absorption Spectrophotometry

提出了用火焰原子吸收光谱法测定高铝锌基合金中镁的方法 ,在测定条件下 ,共存元素的干扰可消除 ,能测定高铝锌基合金中 0 .0 0 1%— 0 .0 1%范围内的镁。该方法相对标准偏差 <6% ,样品加标回收率为94 %— 10 2 %。

The concentration of magnesium in high\|aluminium zinc\|based alloy was determined by flame atomic absorption spectrophotometry.SrCl 2 was used to eliminate titanium,and Mg of which mass concentration is in the range of 0.001%—0.01% can be determined.The relative standard deviation of this method is less than 6% and the rate of recovery is in the range of 94%—102%.
