Abstract：A hydride generation atomic fluorescence spectrometry method has been developed for the determination of trace lead in traditional Chinese medicines. A high pressure digestion using HNO3-H2O2 system was applied for the pretreatment of traditional Chinese medicine samples and the interval flow precedure was used. The experimental conditions and instrumental operatinｇ parameters such as KBH4 concentration, flow rateｓ of carrier and shield gasｅｓ, current of the lamp and height of the atomizer, have been optimized. Under the optimum conditions the detection limit is 0.08 μg·L-1. The ｒｅｌａｔｉｖｅ ｓｔａｎｄａｒｄ ｄｅｖｉａｔｉｏｎ is 0.34%. This method is simple, rapid ａｎｄ sensitive, so it can be successfully used for the determination of lead in traditional Chinese medicines.
