摘要
采用邻菲罗啉分光光度法测定循环水中的铁离子浓度,分析了测定结果不确定度的各种主要影响因素,并求出了测定结果的合成标准不确定度和扩展不确定度,对测定结果进行了表述。
Concentration of ferrum ion in circulating water was determinated by 1,10-phenanthroline monohydrate.The main factors affected determination uncertainty were analyzed.The total uncertainty and the expanding uncertainty of determination result of a sample were calculated.The determination result was formulated.
