| 摘 要： | 对离子色谱法测定烟气脱硫吸收液中的硫酸根离子浓度进行了不确定度评定。通过对标准溶液、标准工作曲线拟合、样品稀释和测定过程重复性等影响测定结果的不确定度分量进行分析,计算出测定结果的扩展不确定度,并找出影响该不确定度的主要因素。

| Abstract: | The uncertainty of the detennaination of the sulfate ion content in the desulfurization absorption solution of flue gas by ion chromatography was researched. The uncertainty components affecting the test result included the standard solution preparing, the standard working euive fitting, the sample dilution and the repeatability of measurement that were analyzed, and the main factors affecting the uncertainty were fund. The expanded uncertainty of the test results was also calculated. |
