分析测量结果是产品质量的重要控制手段和最终判断,而任何测量都有其不确定度。合理科学地分析、计算不确定度既能提高分析测量质量,又能提高对产品质量的判断水平。现根据中国金属学会分析测试分会发布的《分光光度法测量结果不确定度评定规范》(CSM 01010102—2006),对采用铬天青S分光光度法测定生活饮用水中铝含量的不确定度进行评定。1实验部分1.1试剂与仪器铝标准储备溶液:GBW(E)080612,浓度ρ0(Al)
Analysis of measurement results is an important control measure and final judgment of product quality, and any measurement has its uncertainty. Reasonable and scientific analysis, calculation of uncertainty can not only improve the quality of analysis and measurement, but also improve the level of product quality judgment. According to the China Society for Metals Analysis and Testing Branch published “spectrophotometric measurement uncertainty evaluation” (CSM 01010102-2006), the use of chromium Azure S spectrophotometric determination of drinking water aluminum content of the uncertainty assessment. 1 Experimental 1.1 Reagents and Instruments Aluminum standard stock solution: GBW (E) 080612, concentration ρ0 (Al)
