摘要

Trace elements of Cu, Mn, Zn, Al, Fn and Si in magnesium alloy were determined by ICP-AES. The experiment of base-match was simulated and Mg interface was eliminated. The trace Si in the solution can be determined accurately after treated by saturated boric acid solution for F ion. The detection value of the national standard substance ZM3 was agreed to the reference. The detection limits of the method were in the range of 0.003 μg/g～0.053 μg/g with RSDs less than 4% and the recovery of the method ranged from 97.0%～104%.
