Abstract:
The effects of different sample digestives on the determination of Swertia davidii Franch are compared. Eight trace elements in the Swertia davidii Franch were determined by flame atomic absorption spectrometry. The result shows that the RSD and recovery are better if the Swertia davidii Franch was digested with HNO3-HClO4 (5 : 1) mixed acid. The experimental results show that the detection limits were all smaller than 0.097 microg x mL(-1), the RSDs (n=8) all smaller than 2.34%, and the addition standard recovery (ASR) (n=8) was 89.32%-106.65% for all the elements.
