Cu in Reduning injection by ICP-MS was established. Method: The five elements were detected simultaneously after the samples digested by microwave digestion.Internal standard method was adopted to reduce matrix effect and other interference effects. Result: The detectionlimit was 0.009-0.113 μg · L-1. It showed a good linearity in the range 0-20 μg · L-1 (Pb)
0-20 μg · L-1 (As)
0-10 μg · L-1 (Cd)
0-200 μg · L-1 (Cu)
0-5 μg · L-1(Hg);linear relationship is good as r≥0.999.The precision was<1.9%
and recoveries of samples were of the range 97.8%-110.9%.The contents of 5 elements in 20 batches of samples were in In accordance with the provisions. Conclusion: This method is simple
fast
high sensitivity
which can meet the demand for harmful element analysisin Reduning injection.
