Abstract：Twenty-three trace impurities in high purity antimony such as Mg, Al, Si, Ca and Fe were determined by dynamic reaction cell inductively coupled plasma mass spectrometry. The determination isotope was optimized and selected. The spectral interference of Si, Ca and Fe was eliminated with H2 as reaction gas of dynamic reaction cell. The optimal H2 flow rate was established as 4 mL/min. The instrumental signal shift and matrix effect were compensated with Rh as internal standard element. The lower limits of quantitation were in the range of 0.037-0.77 ng/mL, the recoveries of standard addition were 92 %-112 %, and the relative standard deviations (RSD) were smaller than 10 %. This proposed method could meet the requirements for the determination of twenty-three trace impurities in 4N5 high purity antimony.
