气相色谱辅助傅里叶红外光谱用于固定污染源大气醛酮毒物的监测
Gas Chromatography-Fourier Transform Infrared Spectrometry for Monitoring Aldehydes and Ketones Pollutants in the Gas of Fixed Pollution Source
【摘要】 获得了9种大气中常见的醛、酮及甲醇毒物的FTIR系列标准光谱图,建立了用衍生化气相色谱法和非衍生化气相色谱法辅助获得FTIR标准谱图的技术,详细讨论了用人工干预FTIR光谱自动差减法定量分析上述常见醛、酮污染物的可行性问题。
【Abstract】 The Fourier transform infrared (FTIR) standard standard spectra of nine kinds of aldehydes, ketones and methanol were obtained. The possibility for the quantitative determination of these compounds by us- ing FTIR method was discussed in detail. The derivatives and non-derivatives gas chromatographic meth- ods have been used for the calibration of the FTIR standard specie obtained.
