Abstract:
According to the components in soybean，microwave digestion conditions such as masses and kinds of digestion reagents and the procedures design of microwave digestion apparatus were studied in this paper.Using the AFS-820 type Atomic Fluorescence spectrophotometer，trace selenium in soybean was determined under the optimum conditions.The results showed that the recovery rates were from 86.4% to 107.6%，and the detection limit of selenium is 0.12 μg L-1，RSD=3.16%（n=21).
