Abstract:By applying the microwave digestion and atomic fluorescence method for analysis of selenium in eggs.The linear range of selenium was 0-10 ng/mL.The linear correlation coefficient was 0.999 4.The limit of detection was 0.006 ng/mL.The result was that the selenium contents in selenium-rich eggs was far more than ordinary eggs.Meanwhile the different acid degree were compared when prosessing the samples.The results show that under the same condition of 160℃ to get rid of the acid to 1 mL，the contents of selenium was the highest，the recoveres was the most.The standard-addition recoveres of selenium-rich egg was 97.4%-98.8%，and the standard addition recoveres of ordinary eggs was 97.2%-98.5%.
