Abstract:
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 0.045?g?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.
