| Abstract: | The content of six trace elements content including Zn, Cu, K, Fe, Mn, Mg in black rice. from three different area was determined by the microwave digestion and flame atomic absorption spectroscopy (FAAS). The result showed that the method had the advantages of high effectiion, simple, environment - friendly, reagents - saving and the digesting speedy. At that time, the recoveries were between 95.3%～103.5% and values of RSD's obtained were less than 5%. |
