摘要
不确定度是定量表征测量结果质量的一个重要参数。测量不确定度评定现已成为检测和校准实验室不可缺少的工作内容。水中亚硝酸盐氨含量是表征水污染程度的重要指标,因此,对于水中亚硝酸盐氨的测量不确定度评定工作就显得尤为重要。通过评定N-(1-萘基)-乙二胺光度法测定水中亚硝酸盐氮的不确定度,找出了主要影响因素。
Uncertainty is one of the important parameters showing the measurement results quantitively.The measurement uncertainty has become one of the essential jobs for detecting and calibrating labs.The content of nitrite nitrogen in water is an important index characterizing the degree of water pollution.Hence the assessment on the measurement uncertainty of nitrite nitrogen in water is particularly important.In this paper,the main influencing factors were found out by evaluating the uncertainty of nitrite nitrogen in water determined using N-（1-naphthyl）-ethylendiamine spectrmetry.
