紫外荧光法测定环境空气中的SO2
Study on the Portable Ultraviolet Fluorescence Analyzer for Determining SO2 Concentration in the Ambient Air
摘要
Abstract
Objective] The aim was to determine SO2 concentration in the ambient air by using portable ultraviolet fluorescence analyzer.[Meth-od] The monitoring value from the ultraviolet fluorescence and formaldehyde absorbing methods by standard gas samplings and ambient air was discussed through comparison experiment.[Result] The results showed that the two methods have obvious deviation except through the absolute error evaluation when the concentration of SO2 is less than 5μL/m2 ,while the deviation of two methods was less than 10%when the concentration of SO2 is more than 5 μL/m2.[Conclusion] Ultraviolet fluorescence method has advantages of high sensitivity,real-time,wide detection range and good repeatability,which can be used for determining SO2 concentration in the ambient air.关键词
