| Abstract: | Based on the mathematical property of linear least squares,this paper presents the simplified evaluation method for determining the uncertainty of total copper in surface water by using flame atomic absorption spectrometry.Through identification and analyses of uncertainty sources,the paper quantizes the uncertainty and calculates the combined standard uncertainty.This approach is for rapid uncertainty assessment in direct determination method which is applied for determining the total copper content in gro... |
