摘要
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。
Taking Panax notoginseng,Aucklandia lappaDecne.,Rhizoma paridis,Poria cocks and Rhizoma coptis as materials,content of cadmium（Cd）and lead（Pb）in 5different Chinese herbal medicine after separating and enriching with sulfhydryl cotton by flame atomic absorption spectrometry（FAAS）were determined,the enriching and eluting conditions were studied.The results showed that the precision relative standard deviations were between 0.34% and2.86%for determining of Cd and Pb by this method,and the spike recoveries range from 96.32%to 103.70%.The results indicated that the method was reasonable well for determining content of Cd and Pb in Chinese herbal medicine.
