摘要
Abstract
This article according to GB 18585-2001"Limits of hazardous Substances in wallpapers of interior decoration materials",using UV-visible spectrophotometry to detect the formaldehyde content in the wallpaper,and the source of uncertainty in the whole detection process was systematically analyzed.The uncertainty components were quantified,including repeated determination,pipetting of the solution during the experiment,preparation of standard working solution,fitting of standard curve and measuring instrument,and the evaluation method of formaldehyde emission measurement uncertainty in wallpaper was put forward.According to the experimental results,the uncertainty of the determination of formaldehyde content in wallpaper mainly comes from the repeated determination of the sample and the fitting of the standard curve.关键词
