| 摘 要： | 本文建立了氢化物发生-原子荧光光谱法(HGAFS)测定蒜硒的分析方法,方法线性范围是0～60ng/ml,r=0.9997,检出限为0.15ng/ml。将所建立方法用于考察不同施硒土壤中所生长大蒜的硒含量。结果表明:蒜能够富集土壤中的硒,且蒜硒含量与土壤中施硒溶液中硒的含量呈正相关。

| Abstract: | The method of determination of selenium in the garlic was studied. The calibration curve is unear for concentriation range of 0～60ng/ml(r=0.9997). The detection limit is 0.15 ng/ml. The proposed method was applied to determine the selenium content planted in different soils spreaded with different concentrations of selenium. The results showed that the garlic can accumulate selenium from soil, and the selenium content of the garlic is correlated with selenium content in soil. |
