摘要
本文以红外分光光度法对废水中石油类的不确定度进行评定。并对不确定度来源进行分析,包括曲线拟合过程、石油类标准溶液、萃取液定容、量取水样体积等引入的不确定度,对影响结果的各个不确定度分量进行研究分析。并计算出测定结果的扩展不确定度,以此为参考,为今后能更准确检测废水中的石油类提供一定的参考依据。
In this paper,the uncertainty for determination of petroleum in wastewater is evaluated by infrared spectrometry.The sources of uncertainty are analyzed,including the uncertainty introduced by curve fitting process,petroleum standard solution,constant volume of extraction solution,volume of water sample,etc.,each uncertainty component of the influence result is studied and analyzed.The extended uncertainty of the determination result is calculated,which can be used as a reference for more accurate detection of petroleum in wastewater in the future.
