乙酰丙酮分光光度法测定手洗餐具用洗涤剂中甲醛含量的不确定度评定

摘要

Formaldehyde content in detergents for hand dishwashing was measured by acetylacetone spectrophotometry. Analyzed the source of the uncertainty, quantified and evaluated each component of un-certainty via mathematical model, obtained the expanded uncertainty of the measuring results.%采用乙酰丙酮分光光度法测定手洗餐具用洗涤剂中的甲醛含量。通过建立数学模型，分析测定过程中不确定度的来源，对各个不确定度分量进行量化和评定，得出测量结果的扩展不确定度。
