摘　　要：实验在最佳条件下,各组分析标准曲线线性方程相关系数均在0.999以上,回收率在99.2%～102.2%之间。经几种国家标准物质及矿石样品分析方法,结果满意。There are many shortages in the application of catalytic polarographic analysis to the testing of trace Sn, which especially can＇t eliminate the pollution and harm of Hg. The sortages can be remedied by the hydrogenation--atomic fluorescence spectrometry. Under the optimum conditions of experiment, the correlation coefficient of linear equation of standard curve of every analysis is over 0. 999, recovery between 99. 2% - 102. 2%. According to the analysis of various state Standard material and ore sample, the analysis results are satisfactory.
