摘　　要：目的 建立了5种补益类中药材中痕量有害元素铅、砷、汞的含量测定方法。方法 流动注射氢化物发生-原子吸收分光光度法测定铅、砷、汞的含量。结果 测定铅、砷、汞线性范围为0.00-20.00μg·kg-1,仪器精密度RSD<0.51％,加标回收率91.0％-108.0％。结论 本法操作简便、快速,且灵敏度、自动化程度高,适用于中药材中痕量铅、砷、汞的含量测定,结果令人满意。OBJECTIVE: To develop a method for the determination of trace lead, arsenic and mercury in five kinds of beneficial traditional Chinese medicines. METHODS: The contents of the three trace elements were determined by flow injection hydride generation-atomic absorption spectrometry. RESULTS: The linenar ranges were 0.00 ∼ 20.00 μg&middotkg-1. The relative standard deviations were less than 0.51% and the recoveries were 91% ∼ 108%. CONCLUSION: This method is simple, rapid and has been applied to the determination of trace lead, arsenic and mercury with satisfactory results.
