| Abstract: | Emission spectrometry method for the determination of samples of silver and tin .TakingK2S2O7,NaF,Al2O3 and C as a buffer, taking Ge as the internal standard. The detection limit for silver is 0.02μg/g, and the detection limit for tin is 1.0μg/g .Through many experiments, experiment conditions were selected and improved. The method has been applied to the determination of these elements in National Standard Reference Materials and the results are in agreements with certified values. |
