| Research Abstract |
In this study, vapor pressures and thermodynamic data such as standard sublimation enthalpy for bromide metals were obtained using a Knudsen cell apparatus, assuming to a metal recycling process from waste electric and electronic equipment by a pyro-metallurgical process. Vapor pressures of copper bromide, zinc bromide and lead bromide were measured, and their vapor species were identified using a mass spectrometry. Thermal decompositions of brominated flame retardant (BFR) plastics and simultaneous brominating reactions of mixed metal compounds were investigated using a small electric furnace. In the experiments, BFRs such as TBBPA and plastics containing BFR were mixed with metal compounds or electric arc furnace (EAF) dust. The thermal decomposition mechanisms of BFRs and bromide vaporization behaviors of metal compounds were investigated in the experiments.
