| Abstract: | The paper studies the development of the determination of trace metals Zn, Fe, Cu and Mn in tea by flame atomic absorption spectrometry. The method taking HNO3 and H2O2 as oxidation of tea is convenient and correct to determine elements in tea. The results show that the method has good precision and accuracy. The relative standard deviations of Zn, Fe, Cu and Mn were 1.5%,1.9%,3.2% and 0.35%. The determination recovery of the four elements is 92% - 106%. |
