Abstract：Before the analysis of trace elements in pure metals, the matrix effect should be eliminated by matrix re-separation. While, the pretreatment process was complicated, and the sample was easily polluted. The sample was dissolved with nitric acid (1+1). The standard solution series were prepared by matrix matching method to plot the calibration curve. Finally, the content of eight elements including magnesium, chromium, manganese, cobalt, nickel, zirconium, molybdenum and antimony in pure indium was determined by inductively coupled plasma mass spectrometry (ICP-MS). The mass spectral interference was eliminated by selecting proper isotopes. The influence of matrix effect and signal drift was eliminated when magnesium, chromium, manganese and nickel were corrected with 10 ng/mL of scandium, cobalt, molybdenum, antimony and zirconium were corrected with 10 ng/mL rhodium. The experimental results indicated that the mass fraction of elements in range of 1.00-50.0 ng/mL were linear to their corresponding signal intensity, respectively. The linear correlation coefficients were higher than 0.999. The detection limits were between 0.09 ng/mL and 0.78 ng/mL. The proposed method was applied to the determination of magnesium, chromium, manganese, cobalt, nickel, zirconium, molybdenum and antimony in pure indium actual samples. The relative standard deviations (RSD, n=7) were not higher than 10.2%. The recoveries were between 88% and 114%.
