| Abstract: | The lead in Milkvetch Root,Licorice Root and Cablin Potchouli Herb was directly determined by graphite furnace atomic absorption spectrometry after they being digested by HNO3-HClO4（4∶1）.Under the optimum conditions the linear range is 0 ng/mL～20 ng/mL,the detection limit is 0.113 ng/mL,the recovery is 98.2 %～100.9 % and the RSD is 0.2 %. |
