Abstract

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.

Key words: HGAFS(hydride generation-atomic flourescence spectrometry), selenium, accumulation, garlic
