    Determination of silver in copper matte by flame atomic absorption spectrometry……Li Jing

    AbstractFlame 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,andis suitable for the determination of silver in copper matte.

    Keywords:flame atomic absorption spectrometry; copper matte; silver; determination medium;interferehce factor
