以云三七、云木香、重楼、茯苓、黄连为研究对象,通过巯基棉分离富集后,用火焰原子吸收法测定了样品中镉和铅的含量,对镉、铅的富集条件及洗脱条件进行了研究。结果表明:2种元素测定的相对标准偏差为0.34%~2.86%,回收率在96.32%~103.70%之间。该方法可用于测定中药材中镉和铅的含量。 The samples of Yungan, Yunmu, Zhonglou, Fuling and Coptis chinensis were taken as research objects. The contents of cadmium and lead in the samples were determined by flame atomic absorption spectrometry (AFM) And elution conditions were studied. The results showed that the relative standard deviations (RSDs) of the two elements were 0.34% ~ 2.86% and the recovery rates were between 96.32% ~ 103.70%. The method can be used to determine the content of Chinese medicine cadmium and lead.
