Abstract：The acid digestion in open environment is one of commonly used pretreatment methods for the determination of metal elements in stream sediment. The use of different acid systems has great influence on the determination results by inductively coupled plasma mass spectrometry (ICP-MS). With the certified reference material of stream sediment as research object, four acid systems were used to dissolve the sample, i.e., 5 mL HNO3-5 mL HF, 5 mL HNO3-5 mL HF- 2 mL HCl, 5 mL HNO3-5 mL HF-2 mL H2O2, and 5 mL HNO3-5 mL HF-2 mL HClO4. The influence of these four sample dissolution method on the determination of 16 metal elements (including Li, Be, Cr, Mn, Co, Ni, Cu, Zn, Rb, Mo, Cd, Cs, Ba, W, Pb and Bi) by ICP-MS was investigated. Moreover, the significance analysis was conducted based on the measurement data. The results showed that the recoveries of sixteen test elements were between 75% and 120% with 5 mL HNO3-5 mL HF-2 mL H2O2 as digestion medium. During the digestion of stream sediment sample, the digestion effect could be improved by adding substance with strong oxidizing ability into 5 mL HNO3-5 mL HF system. Considering that the Cl in HClO4 would influence the determination of Cr, the HNO3-HF-H2O2 system was adopted. The effect of sample mass on determination results was also investigated. The significance analysis was also conducted based on the measurement data. Finally, 100 mg of sample was adopted. 16 metal elements in certified reference material of stream sediment were determined under the selected experimental conditions. The logarithm error (ΔlgC) between the results and the certified values were all less than 0.13, which could meet the requirements for standard DZ/T 0130.5—2006. The relative standard deviations (RSD, n=6) for Bi (the certified value of 0.03-0.42 μg/g), Cs (the certified value of 113-618 μg/g), Cd (the certified value of 0.11-1.38 μg/g) and Pb (the certified value of 23-102 μg/g) were between 4.7% and 53.0%. The RSD (n=6) of other elements were between 4.0% and 20.5%.
