摘要
采用湿法氧化法对水中总有机碳的不确定度进行了评定。对测量重复性、标准偏差、标准溶液浓度等影响测量结果的不确定度分量进行分析和量化,当水中总有机碳测定结果为5.3mg/L时,扩展不确定度为0.32mg/L。
The uncertainty of measurement was evaluated for the determination of total organic carbon(TOC) in water by wet oxidation method. The uncertainty components of the measurement results, including repeatability of measurement results, standard deviation and the concentration of standard solution were analyzed and quantified. The expanded uncertainty of detection result was 0.32 mg/L as the detection result of TOC in water was 5.3 mg/L.
