摘　　要：对碱片—离子色谱法测定硫酸盐化速率进行不确定度分析评价,应用不确定度理论建立数学模型,对不确定度的来源进行分析和量化,探讨测定结果的不确定度。结果表明,硫酸盐化速率的结果及扩展不确定度为(0.154±0.013)[SO_3,mg/(100 cm^2碱片·d)](k=2),实验过程的不确定度主要来源是样品面积、标准曲线拟合和标准系列配制。This paper assessed the uncertainty of sulfaction rate in air by alkaline sampling paper coupled with ion chromatography.Classified and quantified the uncertainty introduced in the detection process,established a matheematical model for evaluating the uncertainty of the results,and discussed the uncertainty of the determimanation results.The result of the sulfation rate and the expanded uncertainty were(0.154±0.013)[SO3,mg/(100 cm2 paper·d)](k=2).The uncertainty of the experimental process mainly comes from sample paper area,curve fitting and the preparation of standard series.
