摘    要：本文在研究铝对原子吸收光谱法测定镁的干扰规律基础上,利用铝对镁的干扰缓冲特性,建立一种快速测定铝及铝合金中镁的新方法.该法简便、快速,经标样分析表明准确度及精密度均符合要求,适应铝合金生产质量控制的需要.

Abstract: The interference effects of aluminium on the determination of magnesium by atomic absorption spectrophotometry is studied.A new method for determination of high contents of magnesium in aluminium or aluminium alloys is developed.The method is rapid and simple without separating or masking.The recoveries of standard addition are 99.3%～100.4%; the relative standard deviations are in the range of 0.55%～1.2%.Analytical results of reference samples conform to the recommended values.The method can be applied to routineanalysis in aluminium or aluminium alloys industry.
