ABSTRACT
Objective To establish a method for determination of trace lead in alginate sodium.Method The lead in the samples was determined by fluorescence spectroscopy after been digested by hydrothermal decomposition.Results The detection limit of lead was 2.71?10-2?g?mL-1.The relative standard deviation of the three samples were 4.06%,1.57% and 2.12% respectively,the average recovery was 88.32%~100.8%.Conclusion The method had the advantages of simple operation,higher precision,higher sensitivity and repeatability and was suitable for the determination of trace lead in the alginate sodium
