摘要
建立了一种微波消解样品、氢化物发生原子荧光光度法测定中药中汞（Ｈｇ）、砷（Ａｓ）含量的方法。在实验条件下，测定药品中Ｈｇ、Ａｓ平均回收率分别为１０４．１±５．３％，９４．６±１．８％，ＲＳＤ＜５％。本法具有操作简便、快速、准确、灵敏、重复性好等优点，可用于中药中Ｈｇ、Ａｓ的测定。
Determination of mercury and arsenic in herbal medicines by microwave digestion,intermittent flow hydride generation_atomic fluorescence has been performed.The average recovery rates of Hg and As have been proved to be (104.15.3)% and (94.61.8)% respectively by the recovery tests of standard addition to the samples,and RSD of determination of Hg and As is less than 5% under optimum conditions.The method has the advantages of simple and quick operation,high precision,good reproducibility and low interference for the determination of Hg and As in herbal medicines.
