固定污染源废气中氯苯不确定度的评定
Uncertainty Evaluation of Chlorobenzene in Waste Gas from Fixed Pollution Sources
摘要
Abstract
A method for evaluating the uncertainty of chlorobenzene content has been established in the paper.This method uses gas chromatography to quantitatively analyze the content of chlorobenzene in waste gas from fixed pollution sources,and based on an evaluation model,it carries out analysis and evaluation of the uncertainty source through fixed values.The results indicate that when the content of chlorobenzene in the exhaust gas from a fixed pollution source is 2.28mg·m-3,its extended uncertainty is 0.28(k=2).The main influencing factors are the uncertainty introduced by the standard curve and the repeatability of sample measurement,followed by the uncertainty introduced by the stability of the instrument itself.This method can meet the requirements of uncertainty assessment for chlorobenzene compounds in exhaust gas from fixed pollution sources.关键词
