| Abstract: | After milk tea powder disposed by drying method,the constant and trace elements were determined by ICP-OES.Sc was added as internal standard to eliminate the matrix interferences and mixed standard solution series was used to eliminate the spectral interferences.The relative standard deviations（RSD） was less than 3%,and standard recoveries of these elements were in the range of 93.9%—109.4%,and the limits of detection were 0.02—8.77μg/g.The method is simple,quick and accurate for the determination of constant and trace elements in milk tea powder. |
