摘要
按照《近岸海域环境监测技术规范第三部分近岸海域水质监测(HJ 442.3-2020)》,运用连续流动分析仪测定海水中的亚硝酸盐氮质量浓度。根据数学模型把不确定度分解为标准溶液及稀释过程、标准曲线拟合、样品测量重复性和检测方法这几方面引入的。计算不确定度分量,合成不确定度。
According to the "Technical specification for offshore environmental monitoring Part 3 offshore seawater quality monitoring "(HJ 442.3-2020),nitrite in seawater was determined by using continuous flow analysis. According to the mathematical models,the total uncertainty was divided into many pieces,such as the standard material,the dilution process,standard curve,repeatability and detection methods. The uncertainty components were calculated and the synthetic uncertainty was calculated.
