摘要
用4-氨基安替比林分光光度法测定水中挥发酚含量并对测定结果的不确定度进行评定。通过对测定过程中的各种不确定度分析,得到了测定结果的不确定度主要由测量的重复性、工作曲线和标准溶液引入的不确定度组成,其他方面引入的不确定度较小,在实际评定中可以忽略。最后给出了扩展不确定度。
The contents of volatile phenols were determined by 4-aminoantipyrene spectrophotometry and the uncertainty in measurement was evaluated. After analyzing all kinds of uncertainty in determination,it was found that the uncertainty of results was mainly introduced by those of repeatability, working curve and standard solution, but other uncertainty was very trivial and can be neglected in real evaluation. In the end, the expanded uncertainty was presented.
