| Abstract: | The content of trace elements such as Fe, Zn and Mn in red glutinous rice was determined by flame atomic absorption spectrometry （FAAS） with standard method. The sample was digested in V（ HNO3 ） ＋ V（ HClO4 ） = 4 ＋ 1. The results showed that the content of Fe, Zn and Mn in red glutinous rice was 41.95, 31.04 and 18.98μg/g, respectively. The recovery is between 97.4% - 104. 2%, RSD ≤ 4. 1 using the high accuracy and accuracy determination. It concludes red glutinous rice containing the human body essential trace elements Fe. Zn. Mn. |
