摘要
ICP-OES has been applied to the determination of Al、As、Ba、Cd、Cr、Cu、Fe、Mn、Ni、Pb、Se、Zn in tea. In the developed method, matrix effects due to the predomient matrix elements and the spectral interference between the analytes was studied. The recovery Values found in the analysis of spiked sample ranged from 91.7%to 113.8%, and the RSD Value from 0.80% to 9.4%.
