| Abstract: | The 20 impurity elements of fine silver were determined by the spark direct reading spectrometric method. The content of silver was calculated by the subtraction method in the percentage of weight. The method of sample preparation and analysis method were studied. The experimental results are stable, reliable, reproducible and suitable for measuring silver content of 99.9%~99.99%. |
