| Abstract: | Various test conditions and effect factors for the determination of selenium by flow injection-hydride generation-atomic absorption spectrometry were discussed and a method for the determination of selenium in tricholoma giganteum has been developed. The linear range for selenium is 0-50 microg x L(-1). The relative standard deviation is less than 3% and the recovery is 96%-105%. This method is simple, rapid and has been applied to the determination of selenium in tricholoma giganteum with satisfactory results. |
