摘要:
目的：评定采用电感耦合等离子体质谱法(ICP-MS)测定黄芪中铅、镉、砷、铜含量的不确定度。方法：使用ICP-MS法测定黄芪中铅、镉、砷、铜的含量，分析测定方法流程，确定不确定度来源，并计算扩展不确定度。结果：铅、镉、砷、铜的扩展不确定度分别为Pb 0.13 mg/kg，Cd 0.052 mg/kg，As 0.21 mg/kg，Cu 0.17 mg/kg。结论：该方法适用于ICP-MS法测定黄芪中铅、镉、砷、铜的不确定度评定，能为重金属分析过程的不确定度评定提供了参考。
Abstract:
Objective: To evaluate the uncertainty of determination of Pb, Cd, As and Cu content in HuangQi (Radix Astragali) by the methods of inductively coupled plasma mass spectrometry (ICP-MS). Methods: ICP-MS method was used to determine the contents of Pb, Cd, As and Cu in HuangQi. The measurement process was analyzed, and the source of uncertainty was determined. In addition, the extended uncertainty was calculated. Results: The extended uncertainty of Pb was 0.13 mg/kg with Cd 0.052 mg/kg, As 0.21 mg/kg, and Cu 0.17 mg/kg. Conclusion: This method is suitable for the evaluation of the uncertainty of determination of heavy metals in HuangQi by ICP-MS. Besides, it provides a reference for the uncertainty evaluation of heavy metal analysis process.
