| Abstract: | A method by atomic absorption spectrometry has been proposed for the determination of trace metal elements in grain samples. And 11 elements (Cu, Zn, Fe, Mn, Ca, Na, Mg, K, Pb, Cd, Cr) in Huishui purple glutionous have been analyzed. The digestion treatment of grain samples, the experimental conditions (for determination of standard solution), the sensitivity and detection limit of this method were given. The accuracy of the method was practised by the national standard material of grain. All of the results show that the analytical method is accurate and reliable. |
