| 摘 要： | 采用氯化镉、氯化氨作反应剂，以背景为内标，在WSP-1型平面光栅摄谱仪上摄谱进行化探样品中微量银的测定。方法线性范围为0．02—5．0μg／ml，6次测定相对偏差为1．68％-3．39％，测定值与推荐值基本相符，能满足化探样品中痕量Ag的分析要求。

| Abstract: | Taking Cd chloride and ammonia chloride as the reaction agent, background as inner standard, we analyze the trace Ag of geochemical sample with WSP - 1 plane grating spectrometer. The linear range of method is 0. 02 -5μg/ml. The relative error of 6 teats is 1.68 - 3.39%. In the test of standard sample, the testing value is basically consistent with the recommendation value, which can meet the basic requirement in testing trace Ag in geochemical sample. |
