DISTRIBUTION OF HALOGENATED PHENOLS INCLUDING MIXED BROMINATED AND CHLORINATED PHENOLS IN MUNICIPAL WASTE INCINERATION FLUE-GAS

Incineration of municipal waste yields a variety of halogenated phenol s including chlorinated, brominated and mixed brominated and chlorinat ed phenols in raw and stack gas. A total of 14 chlorinated, 3 brominat ed and 31 mixed brominated and chlorinated phenols could be characteri zed by high resolution gas chromatography high resolution mass spectro metry (HRGC-HRMS). A significant molar fraction of halogenated phenols in raw and stack gas was found to be monobrominated (12% and 8%) and dibrominated (2% and 1%). The monitored fraction of polyhalogenated ph enols can be characterized with an elemental composition of C6H2.6Br0. 2Cl3.2O in raw and C6H2.5Br0.1Cl3.4O in stack gas.
