Abstract: A simple method based on the dynamic reaction cell (DRC) technology to eliminate the spectral interference in the simultaneous determination of trace cadmium and silver in soil samples by ICP-MS was established. Under the optimized O 2 flow rate (2.7 mL min-1) and the DRC rejection parameter RPq (0.8 for Ag, 0.7 for Cd), the interference caused by Zr, Nb, and Mo (such as 95 Mo 16 O + , 94 Mo 16 OH + , 94 Zr 16 OH + on 111 Cd + and 93 Nb 16 O + , 92 Zr 16 OH + on 109 Ag +) could be effectively eliminated, and t…
