摘要(Abstract)：

目的探索建立中药材中汞的原子荧光光谱检测方法,为《中国药典》收载原子荧光光谱法提供实验基础。方法采用原子荧光分光光度法测定常见中药材中汞的含量,并对测定方法进行方法学考察。结果采用本文所用检测方法的标准曲线相关系数r=0.999 9,加样回收率为98.7%,RSD为2.3%。结论方法简便快速、准确灵敏,比现行药典冷原子吸收法缩短了大量时间,为中药材的重金属控制技术提供一种新的参考方法。
OBJECTIVE To establish the atomic fluorescence spectrometry method for the determination of mercury in traditional Chinese medicines. To provide experimental basis for the atomic fluorescence spectrometry method collected in Chinese Pharmacopoeia.METHODS Mercury in traditional Chinese medicines was analyzed by atomic fluorescence spectrometry method, and the determination method was studied by methodology. RESULTS The results showed that the correlative coefficient of calibration curve was 0.999 9,the recovery was 98. 7% and RSD 2. 3%. CONCLUSION The method is convenient,quick,accurate and sensitive,which can shorten a lot of time for the determination of mercury by cold atomic absorption spectrometry. Also,the method can be used as a new reference method for the control of heavy metal in traditional Chinese medicines.
