摘要
Taking Cd chloride and ammonia chloride as the reaction agent, background as inner standard, the authors analyzed the trace Ag of geochemical sample with WSP-1 plane grating spectrometer. The linear range of method is 0.02～5 μg/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.
