| Abstract: | Objective To investigate fluorometric determination methods of trace elements selenium.Methods The traditional method of preconditioning technology of the biological samples was to be improved.Results This determination methods was better with the lowest detectable rate (0.23?ng), the coefficient of variation being(CV%) 1.6～4.8%, and the average recovery rate 99.5%.Conclusion The advantages of this method include less samples, easy management and better reappearance. |
