摘要
目的测定7种藻类植物药中汞的含量。方法用微波消解系统消化样品,原子荧光光谱仪测定。结果测定汞的检出限为0.045(g.L-1,相对标准差(RSD)=1.65%,平均回收率为97.77%。结论该法具有操作简便、准确、灵敏、重复性好等优点,可用于7种藻类植物药中汞的含量测定。
Objective To determine the mercury in seven kinds of algal plant drugs. Method The mercury in the samples was determined by the atomic fluorescence spectrometry after been digested by microwave. Results The detection limit of mercury was 0. 045μg · L^-1. The relative standard deviation was 1. 65% and the average recovery was 97.77%. Conclusion The method had the advantages of simple operation, higher precision, higher sensitivity and repeatability and was suitable for the determination of mercury in the algal plant drugs.
