摘　　要：发射光谱法同时测定地球化学样品中Ag、Sn、Pb元素,具有操作便利、分析快速、定量准确等优点。同时也存在诸多导致测试结果不稳定的因素,本文通过选择适宜的分析线波长、球磨仪研磨样品的适宜重量、实验样品与缓冲剂的最佳混合比例进行实验讨论,最终选择出最佳试验条件供参考。The simultaneous determination of Ag,Sn and Pb elements in geochemical samples by emission spectrometry has the advantages of convenient operation,rapid analysis and accurate quantification.At the same time,there are many factors that lead to the instability of the test results.In this paper,the author discusses the experiment by selecting the appropriate wavelength of the analysis line,the appropriate weight of the sample grinding by the ball mill,and the optimal mixing ratio of the experimental sample and buffer.Finally,the optimal test conditions are selected for reference.
