摘要
力求全面分析重铬酸钾法测定水中化学需氧量测量不确定度的来源,并以实例演示了化学需氧量测量不确定度的评定全过程。
The reasons of detecting uncertainty of chemical oxygen demand detection with potassium dichromate method are tried to be found out. The whole process of evaluation of uncertainty of chemical oxygen demand detection with potassium dichromate method is displayed with a real case.
