| Abstract: | The sample is dissolved~in aqua regia and silver is leached by ammonia, most other metallic elements are precipitated at the same time, eliminating the interference. In 10 % hydrochloric acid medium, under the set equipment working conditions, silver content was determined by flame atomic absorption spectrometry. The relatively standard deviation of the determination results is less than 1%. |
