Abstract

A home-made analytical instrument based on thermal desorption gas chromatography coupled to resonance enhanced multiphoton ionization time-of-flight mass spectrometry (TD-GC-REMPI-TOFMS) was applied for atline measurement of 1,2,4-trichlorobenzene for the prediction of polychlorinated dibenzodioxin and dibenzofuran (PCDD/F) concentrations in the stack gas of a municipal solid waste incinerator (400 ton/day). Conventional high resolution gas chromatography/high resolution mass spectroscopy (HRGC/HRMS) measurements for the determination of PCDD/F concentrations were performed to compare with TD-GC-REMPI-TOFMS measurements. 1,2,4-Trichlorobenzene correlated with I-TEQ at r = 0.867, 0.953 and 0.944 in unstable, stable and integrated conditions. The correlation was independent of the facility operating conditions observed in this study. Using a linear model to predict I-TEQ by 1,2,4-trichlorobenzene over the test, the average of the relative difference between predicted and measured I-TEQ was 18.9%. 1,2,4-Trichlorobenzene measured by TD-GC-REMPI-TOFMS can be used as a robust indicator of I-TEQ in stack gas.
