The Quantitative Analysis of Combustion Gases from Interior materials of Rail passenger car by using FT-IR Spectroscopy

초록

In this study, quantitative determination of nine different toxic gases in fire smoke has been investigated using FT-IR (Fourier Transform Infrared) spectroscopy. Calibration curves were initially built using individual standard gases of asphyxiant gases (CO, CO2 and HCN), irritant gases (HCl, HBr and HF), nitrogen oxides (NO and NO2) and SO2. IR spectra were collected for gases released from combustion of the interior materials of railway vehicles. Since water spectral features were dominant and overlapping with those of some gases, the water spectral features was initially subtracted and the resulting subtracted spectra were used to develop quantitative calibration curves for all gases. The quantitative analysis results using IR spectroscopy were in good agreement with those from other analytical methods
