| Abstract: | In this article, the author discussed a method for determination of selenium in Silver vanadium by inductively coupled plasma mass spectrometry. The samples were dissolved by HNO3-HCl-HClO4 solution. An internal standard method was used to eliminate possible mass spectral interference. The results indicated that the detection limit of selenium was 0.066 3 ng/mL, with the recoveries of 94%~106% and the relative standard deviations(n=7) less than 5.0%. Because of its simplicity, speediness and accuracy, this method can be used in the determination of antimony elements in insoluble lead concentrate . Moreover, it is also suitable for the determination of selenium content in silver vanadium. |
