Abstract: |
The spectral interference level of stannum(Sn) in the determination of cadmium(Cd) by inductively coupled plasma mass spectrometry (ICP-MS) was investigated with different concentration ratio of Sn/Cd under different work conditions. The content of Cd was obtained by on-line and off-line interference corrections, respectively, which was consistent with the certified value. The results show that: the contents of Cd maintained good agreement with the certified value without any interference corrects when the concentration ratio of Sn/Cd was below 2 and the effect of Sn on Cd determination was negligible; the contents of Cd corrected by on-line and off-line interference were in accordance with the certified value when the concentration ratio of Sn/Cd was in the range 2~30; satisfactory results were obtained only by off-line interference when the concentration ratio of Sn/Cd exceeded 30. |
