摘要
通过用乙酰丙酮分光光度法测定纺织品中甲醛的含量,详细分析和评定测定过程中影响结果的各个不确定度分量。研究表明:样品中甲醛含量为73.8±2.1mg/kg,置信概率近似95%。该测量过程所产生的不确定度主要来源于重复性、标准曲线和萃取液体积三方面。
The formaldehyde content in textile is determined by the acetylacetone reagent using a spectrometer. The analysis results show that the formaldehyde content of sample is 73.8 ± 2.1mg/kg（confidence level=95% ） and the measurement uncertainty of formaldehyde in tex -tile comes mainly from the process repeatability , standard curve and the volume of extract -ed solution.
