摘要
研究了原子吸收光谱法测定铝合金中锑,试验了酸度及干扰离子对锑含量的影响,进行了回收实验精密度试验。实验表明该方法操作简单,准确度好。锑的回收率在97%～102%之间。相对标准偏差在0.94%～1.57%。
A method for the determination of Sb in aluminum alloy by flame atomic absorption spectrometry was studied,and the effect of acidity and interfering iron on Sb content was examined by tests.The results of recovery and precision test show that the method was simple and easy,and the accuracy is high.The recovery of Sb is in the range of 97%～102%,and the relative standard deviation is within 0.94%～1.57%.
