[Determination of selenium in selenium-enriched foods by hydride generation atomic absorption spectrometry].
OBJECTIVE
To determine selenium (Se) in selenium-enriched foods by hydride generation atomic absorption spectrometry.


METHODS
The samples were digested by HNO3-HCLO4 and reduced by NaHB4, and then was determined in 6 mol/L HCL.


RESULTS
The results showed that the detectable range, detection limit, recovery rate, and the relative standard deviation(RSD) of the method were 0 - 80.0 microg/L, 0.0056 mg/kg, 92.05% - 103.88%, and 1.34% - 3.81% respectively.


CONCLUSIONS
This method is suitable for selenium determination.
