| Abstract: | A method for the determination of trace selenium in Hygienical Foods by the intermittent flow-hydride generation atomic fluorescence spectrometry has been developed with high sensitivity and fine accuracy.Under the selected experiment conditions,there is a linear relationship between the fluorescence intensity and selenium concentration in the range of 0.7~280 ng·mL-1 with correlation coefficient of 0.9996,the limit of detection is as low as 0.2 ng·mL-1.The recovery is 96.5%~101.0%,and the RSD is not more than 1.47%. |
