1 引言 1990年美国公布的新空气清洁法中列出了9种重点控制的醛酮污染物:由于FTIR光谱法具有快速、方便等特点,很适合于现场分析,所以美国国家环保局希望FTIR光谱法能成为固定污染源大气毒物现场监测方法。我们曾建立了FTIR光谱自动差减定量软件及醛酮的FTIR标准谱图库,并探讨了将其用于定量的可行性问题。本文将其用于北京第三有机化工厂乙醛车间工艺尾气的现场监测。该厂废气经吸收塔后直接放空。2 实验部分
1 INTRODUCTION Nine major controlled aldehyde and ketone pollutants are listed in the 1990 U.S. Clean Air Act: FTIR spectroscopy is suitable for on-site analysis due to its fast and convenient characteristics. Therefore, the US Environmental Protection Agency wants FTIR spectroscopy France can become a fixed source of air pollution monitoring methods. We have established the FTIR spectrogram library of FTIR spectral auto-subtraction quantification software and aldehydes and ketones, and discussed the feasibility of using it for quantification. This article will be used for the third organic chemical plant in Beijing acetaldehyde workshop process tail gas on-site monitoring. The factory waste gas directly after the absorption tower emptying. 2 experimental part
