| Abstract: | Pure silver with the purity of 99. 85%~99. 99% is determined by nitride precipitation-flame atomic absorption spectrometry. The best working conditions for the instrument, the influence of time, precision and comparison are tested. The standard deviation is less than 0.08% through the multiple determination of standard silver and sample silver. The method is simple, time saving and accurate. |
