摘要
目的对4-氨基安替比林分光光度法测定水中挥发酚的不确定度进行评估,探讨该方法测定的置信度和准确度。方法找出影响不确定度的各种因素,对不确定度进行评估,给出该分析项目的测量不确定度。结果本方法的检出限为0.002 mg/L,当样品测量浓度为0.030 mg/L时,其测量的扩展不确定度为0.0023 mg/L。结论本分析方法实用于水中挥发酚测定的不确定度评估,如实地反映了测量的置信度和准确度。
Objective To evaluate uncertainty in measurement of phenols in the water.Methods The factors which affect the degree of uncertainty in measurement of phenols were found out and the evaluation of uncertainty in measurement of phenols was given.Results Detection limit of this method was 0.030mg/L.Spread degree of uncertainty in measurement of phenols in the water was 0.0023mg/L when the concentration of sample was 0.030 mg/L.Conclusions The method introduced in this paper can be used in the evaluation of degr...
