Abstract：0.100 0 g of sample was dissolved with 10 mL of nitric acid (1+1) by heating from low temperature to boiling. Based on the optimization of instrumental parameters, the mass spectrometry interference was avoided by selecting proper isotope, and the calibration curve was plotted by standard addition method to eliminate the matrix effect. Consequently, a determination method of arsenic, tin, antimony, lead and bismuth in high-purity nickel plate was established by inductively coupled plasma mass spectrometry(ICP-MS). The correlation coefficient of calibration curve for each element was between 0.999 2 and 0.999 9. The detection limit of method was 0.009-0.047 μg/g. The proposed method was applied to the analysis of high purity nickel plate actual sample. The relative standard deviation (RSD, n=9) was 2.4%-5.4%, and the recoveries were between 95% and 106%. The determination results of high purity nickel plate actual sample were consistent with those obtained by atomic absorption spectrometry (AAS).
