| Abstract: | Cadmium and lead in the Tripterygium wilfordii Hook were determined by flame atomic absorption spectrometry. The results showed that the RSD and recovery were better if the Tripterygium wilfordii Hook was digested with mixture of HNO3 and H2O2 (5:2). The experimental results showed the limits of detection were 0.25 μg.mL-1 and 0.036 μg.mL-1, The relative standard deviation (RSD) were 2.5% and 3.7%(n=5), the recoveries were 97% and 101% respectively for lead and cadmium. |
