摘要: A model for predicting the distribution of dibenzofuran and polychlorinated (PCDF) congeners from a phenols was developed. The is based on simplified chemical mechanism. Relative rate constants reaction order with respect to phenol precursors were derived experimental results using single equal molar mixtures up four phenols. For validation, experiments performed at three temperatures 19 chlorinated as measured in municipal waste incinerator exhaust gas. Comparison measurements predictions PCDF isomer distributions homologue pattern shows agreement within measurement uncertainty. R-squared correlation coefficient exceeds 0.9 all homologues. These demonstrate that 135 gas-phase condensation can be predicted congeners.
