摘要
采用比浊法测定某生产工艺废水中硫酸根浓度,确定比浊法检测硫酸根含量不确定度来源,对比浊法测量硫酸根结果的不确定度进行评定,结果表明,比浊法测定废水中硫酸根含量为1 567 mg/L,扩展不确定度为42 mg/L,不确定度的最大来源是拟合标准工作曲线的波动性。
The turbidimetric method was used to determine the concentration of sulfate in a waste water from a production process. The source of uncertainty was determined and evaluated by turbidimetric method for detection of sulfate content.The results showed that sulfate content of 1 567 mg/L by the turbidimetric method,extended uncertainty of 42 mg/L,and the greatest source of uncertainty is the volatility of fitting of the standard working curve.
