Abstract

Thermodynamic considerations indicate that heavy metal oxides should easily react with HBr, the main gaseous product from the thermal decomposition of tetrabromobisphenol A (TBBPA), forming low boiling point metallic bromides suitable for volatile separation. Mechanisms and kinetics of the bromination reactions must be well recognized prior to developing of a new treatment for the simultaneous recycling of plastic waste containing brominated flame retardants (BFRs) and metal oxides (printed circuit boards, automotive shredder residue, plating sludge, metallurgical dusts). In this work, a differential scanning calorimeter and laboratory-scale furnace were used to investigate the possibility and conditions of the bromination of ZnO by product of thermal decomposition of TBBPA. The formed solid, condensed and gaseous products were analyzed by X-ray diffraction analysis, electron probe microanalysis, inductively coupled plasma analysis, ion chromatography and gas chromatography coupled with mass spectrometry.
