| Abstract: | Flame atomic absorption spectrometry is established to determine silver in copper matte.The samples are dissolved by nitric acid and perchloric acid,and in 15 ％ hydrochloric acid medium,silver is determined by atomic absorption spectrometry.The correlation coefficient of the standard curve is 0.999 9,the linear range is 20.0-300.0 g/t,the relative standard deviation is 2.02％ - 3.07 ％ . and the recovery rate of standard substance is 99.3％- 103.1％.The method is simple ,fast , accurate and reliable,and is suitable for the determination of silver in copper matte. |
