Abstract:

This article studied effects of conditions of instrument, current-carrying and potassium borohydride concentration on fluorescence single value of selenium, and established a quick and accurate method to determine organic and inorganic selenium in soybean. This method successfully eliminated the disturb of coexisting ions on the detection of selenium, and the results showed that the detection limit is 3.6 ng/L, the recovery is 86.7% to 105.0%, and the relative standard deviation is 1.95% to 4.52%.

Key words: AFS, soybean, organic selenium, inorganic selenium
