摘要
对影响甲醛吸收-副玫瑰苯胺法测定空气中二氧化硫含量的因素进行了辨别,根据测量不确定度的方法,建立了测定不确定度方法,系统地分析了影响测定结果可靠性的关键环节和主要因素。通过计算和评定,得出了该方法测定二氧化硫不确定度为:0.014μg/mL。
The factors affecting the determination of sulfur dioxide in the air by formaldehyde absorption-para-rose benzamine were identified.According to the method of measuring uncertainty,a method of determining uncertainty was established,and the key links and main factors affecting the reliability of the results were systematically analyzed.Through calculation and evaluation,it is concluded that the uncertainty of the determination of sulfur dioxide by this method is 0.014μg/mL.
