摘要
通过对盐酸副玫瑰苯胺法测定白砂糖中二氧化硫的测定过程进行研究,分析了该法测定结果的不确定度分量及其来源,确定了各不确定度分量值,给出了该法的扩展不确定度。
Through the research on the detemaination of SO2 in white granulated sugar by pararosaniline hydrochloride method, the sources of uncertainty components were analyzed, and the individual uncertainty values were evaluated, the expanded uncertainty of the method was given.
