| Abstract: | Se (IV) and Se (VI) in crop samples were determined by High-performance liquid chromatography-atomic fluorescence spectrometry (afs) after 0.45 m filtration and ultrasonic extraction with Monopotassium phosphate-cupric sulfate solution. The detection limit of this method is 1.5 g/kg Se (IV) and 1.5 g/kg Se (VI) . The precision (RSD) of the method was 5.8-8.2% and the recovery was 81.5%-92.5% . |
