英文摘要:

      Objective To establish an uncertainty assessment method for dairy lead determination by atomic absorption spectrometry. Methods The uncertainty measurement analysis method was used to evaluate the uncertainty sources in the process of determination. Results The uncertainty had been got, and the reliability and accuracy of the measurement had been truthfully reflected. Conclusion This method of uncertainty evaluation has a strong practical value in the atom absorption analysis work.
