提出了用火焰原子吸收光谱法测定高铝锌基合金中铜含量的方法 ,在本法测定条件下 ,基体元素及其他共存元素不干扰 ,可测定质量分数为 2 .0 %— 3.0 %范围内的高铝锌基合金中的铜。该方法相对标准偏差为 0 .96 7%,样品加标回收率为 98.4%。
A flame atomic absorption spectrometry method for the determination of copper in high-aluminum-zinc-based alloys was proposed. Under the conditions of this method, the matrix elements and other coexisting elements do not interfere with each other. The mass fraction of copper can be determined within the range of 2.0% to 3.0% Copper in high-Al-Zn-based alloys. The relative standard deviation of the method was 0.96 7%, and the spiked recoveries of the samples were 98.4%.
