Abstract:In the present paper, microwave digestion technique was used to determine Ca, Zn, Cu, Mg and Fe in rat liver by flame atomic absorption spectrometry (FAAS). The effect of microwave digestion condition on the analysis results was examined and the best analysis condition of FAAS was selected. Compared to traditional wet methods, the experimental result showed that the method is rapid, sample digestion is complete, the blank value is low, and the measurement result is satisfactory. Applied to the determination of trace elements in rat liver, the method proved to be selective with satisfactory recovery of 96%-103% and relative standard deviation of 1.0%-2.6%.
