摘　　要：对溶样方法及酸加入量对吸光度的影响、基体铝和铜等元素对镉的测定干扰等内容进行了研究 ,选择了最佳实验条件 ,该方法精密度 (相对标准偏差 )为 3 .7% ,相对误差 3 .8% ,回收率为 :96 %～ 10 6 %。研究结果表明 ,该方法快速 ,准确可靠 。The flame atomic absorption method to analyze the cadmium in cast Al-Cu alloy is reported in this paper. The following contents are studied in this paper, including the digestion method, the influence of the acidity to the Cadmium's absorption, the interference of the matrix aluminum and copper to cadmium, etc. The optimized experimental condition is obtained after the condition experiments. The analysis accuracy( RSD %) of this method is 3.7%. The relative error( E r) is 3.8%. The recovery of the spike is from 96% to 106%. The research result proved that this method is fast,precise and reliable, and can meet the requirement of the analysis precision.
