| Abstract | The effects of four types of graphite tube and five matrix modifiers on the determination of selenium by graphite furnace atomic absorption spectrometry were compared. The results show that platform thernolysis coat graphite tube and magnesium nitrate and cobaltco as matrix modifer can get a high sensitivity and a good recovery. The optimized working conditions and interference in the determination were invesigated. This result is consistent with that of XRF. The recovery is from 100.8% to 102.2%, the relative standard deviation is from 3. 47% to 5.56% (n=9), and the detection limit of selenium is 378 pg (C=44.5 μ/g to 97.3μg/g.). The proposed method can be applied to the rapid determination of selenium in electrolytic manganese. |
