[Objective]To establish a new method for simultaneous determination of selenium(Se) and tellurium(Te) in wet-digestion prepared spirulina powder by hydride generation-double channel atomic fluorescence spectrometry.[Methods] After digestion with HNO3-HClO4,HCl solution was added for the reduction of Se6+/Te6+into Se4+/Te4+,which acted with KBH4solution.The concentrations of Se and Te were estimated by standard curve method.[Results]The calibration curve of Se was linear within the range of 2.70~20.00μg/L wi...
