摘  要:
目的:建立一种有效、可靠的方法测量饮用水中铜的含量是否超标。方法:采用火焰原子吸收法测定水样中铜的含量,并对测量结果进行不确定度分析。结果 :水样中铜的浓度为0.232μg/mL,测量结果的扩展不确定度为U=0.07μg/mL,k=2。结论 :用该方法测定水中铜的含量快速、准确,测量结果符合GB5749—2006《生活饮用水卫生标准》的规定。

摘  要:
【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.【Result】 The concentration of copper in water samples was 0.232μg/mL,and expanded uncertainty of measurement results was U=0.07μg/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.
