摘要
采用石墨炉原子吸收光谱法测定镁基合金中的铍和镍.研究并校正了基体对待测元素的影响.方法简单、快速.对含铍11.4×10-6、镍9.25×10-6的样品11份测定,相对标准偏差分别为3.5%、4.3%,铍、镍回收率分别为98.8%、97.5%.
Beryllium and nickel in magnesium-based alloys can be determined by the method of graphite furnace atomic absorption spectrometry. The influence of matrix effect is studied and corrected. The method is simple, quick and easy to operate. The samples （n = 11 ） with Be of 11.4 ×10^-6 and Ni of 9.25 ×10^-6 are analyzed. The precisions （RSD） are 3.5% and 4.3%, respectively. The recoveries of Be and Ni are 98.8% and 97.5%, respectively.
