| Abstract: | Selenium tablets samples were dissolved in HNO3-HClO4(4:1) mixed acid, and the elemental compositions were analyzed by inductively coupled plasma-atomic emission spectrometry.The results showed that the contents of Se, Fe, Ca, and Zn were relatively rich in selenium tablets.This method issensitive and simple.The relative standard deviations(RSDs) were less than 3%, and the recoveries were 96.5 %~101%.The results could provide a reference for studying the health care function of the selenium tablets. |
