Abstract:

An efficient method was established to simultaneously determinate metal elements such as Ca, Mg, Fe, and Zn
in blueberries using high resolution-continuum source flame atomic absorption spectrometry.after wet digestion. Using
the established method, the contents of Ca, Mg, Fe, and Zn in blueberries were determined to be 100.3, 55.80, 2.330 and
1.413 mg/kg, respectively. The limits of detection (LOD) were 0.030, 0.830, 0.088 and 0.049 mg/L, respectively. The mean
spiked recoveries for these metal elements ranged from 94.6% to 107.0% with relative standard deviations between 1.9%
and 4.7%. This method was suitable for simultaneously determining several metals elements with the advantage of high
efficiency, good stability and easy operation.
