| Abstract: | A method for the simultaneous determination of antimony and bismuth in silver ingot by hydride generation-atomic fluorescence spectrometry with precipitation separation was proposed.The detection limits of the method for bismuth and antimony were 0.02mg/kg and 0.002mg/kg,the recoveries were 91% -96% and the relative standard deviations were below 1.2%.The results indicated that the method could be applicable to the simultaneous determination of antimony and bismath wirth high sensitivity and accuracy.The analytical results were quite consistent with those by national standards method. |
