| Abstract: | A new method for determination of the bismuth in silver powder by flame atomic absorption spectrometry is presented in this paper. The impurity of bismuth is gathered by iron hydroxide and separated with silver, and then determined by atomic absorption spectrometry. This method is rapid, simple, convenient and accurate, and can meet the requirement of rapid monitoring and analysis in production of silver products. |
