Abstract
The determination method for the content of trace element of Cu, Fe, Mn, Zn and Ni in tea by the wet digestionflame atomic absorption spectrometry (FAAS) was established. The effect of digestive reagents, the volume of digestion and the digestion time were investigated in detail. The optimum condition for digesting samples was HNO3-H2O2 system; the volume of H2O2, 4 mL; and digestion time, 60 min. The content of Fe in the analyzed samples was 115.62 g/g, while the content of Cu was 42.54 g/g, Mn 396.48 g/g, Zn 50.69 g/g, and Ni 14.88 g/g. The recovery of the five elements was in the range of 96.37 103.92 %. Relative standard deviation (RSD) was less than 5 %. This method was simple, higher precision and accuracy. And experiment results were satisfactory.
