Abstract 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.
