Flame atomic absorption spectrometry(FAAS) was applied to determinate eight metal elements,Zn,Na,Mg,Fe,Ca,Cu,Mn,Sr,in three kinds of pearl powder bought from market.The samples were digested with a mixture of HNO3 and H2O2(6∶ 1,φ) in a microwave and then detected by FAAS.Detection limits(3S/N) for eight elements were in the range of 0.000 6~0.024 8 mg/L.The recoveries were in the range of 95%~105% and RSD(n=10) was lower than 5%.The distribution of 8 metal elements in 3 kinds of pearl powder were similar.Ca was the most which was more than 34.15%.Mn,Sr,Fe,Na were more than 94.74 μg/g while Zn,Mg,Cu were less than 11.78 μg/g.The content of Ca indicated the quality difference among 3 kinds of pearl powder.The lower the content of Ca was,the worse the pearl powder's quality was.This paper provides a new and useful method for quality assessment of pearl powder by the contents of metal elements.
