| Abstract: | Objective To research the contents and species of metal elements in the rice. Methods Waterish digestion and ICP-AES were used to determine the metal elements in the rice. Results Detection lines is （0.04 1. 21 ） × 10^-4, and its recovery ratio obtained by standard addition method ranged between 92.0% and 111.9% ,while RSD is 0.4% - 3.8% . Conclusion There are kinds of metallic elements in the rice by using ICP-AES, the contents of K, Mg, Ca, Zn, Mn, Fe are very abundant. |
