摘要

Abstract

[Objective] To establish an effective and reliable method to determine whether copper content in drinking water is excessive. [Method] Copper content in water was determined with flame atomic absorption method, and the uncertainty was analyzed, lResult] The concentration of copper in water samples was 0. 232μg/mL, and expanded uncertainty of measurement results was U =0. 07μ g/mL and k = 2. [Conclusion] This method was fast and accurate to determine copper content in water. Measurement results were in line with GB5749- 2006 Sanitary Standard for Drinking Water.
