Open publisher page 0 citations

Abstract

In fuel-fired power plants, error resulting from test process of copper content should be decreased to minimum because trace copper is in the steam-water. 100μg/mL copper reference solution is prepared in the laboratory and its concentration is determined by means of EDTA compleximetry. Then the uncertainty is analyzed and calculated from every factor. The result shows that the expanded uncertainty of 100μg/mL copper reference solution is 0.6μg/mL.
