The thermal treatment of waste electrical and electronic equipment (WEEE) is regarded as the largest potential contributor to the environmental release of polybrominated dibenzo-p-dioxins/dibenzofurans (PBDD/Fs). Herein, the pyrolysis of decabromodiphenyl ether (deca-BDE), polyethylene (PE) and metal blends was conducted to investigate the emission characteristics of PBDD/Fs at different thermal treatment conditions. The total yield of polybrominated dibenzo-p-dioxins (PBDDs) was less than that of polybrominated dibenzofurans (PBDFs) during the pyrolysis of the PE matrix and metal blends. 2,3,7,8-TBDF and 1,2,3,7,8-PBDF were the dominant congeners emitted from the pyrolysis. Temperature, presence of oxygen and type of added metal were the critical influencing factors for the PBDD/F formation rates and speciation in the pyrolysis process.
电子电气废物（WEEE）的热处理被认为是最大的潜在环境释放多溴二苯并二恶英/呋喃（PBDD/Fs）源。在此，对十溴二苯醚（deca-BDE）、聚乙烯（PE）和金属混合物进行了热解，以研究不同热解条件下 PBDD/Fs 的排放特性。在 PE 基质和金属混合物的热解过程中，多溴二苯并二恶英（PBDDs）的总产率低于多溴二苯并呋喃（PBDFs）。2,3,7,8-TBDF 和 1,2,3,7,8-PBDF 是热解过程中排放的主要同系物。温度、氧气的存在和添加金属的类型是热解过程中 PBDD/F 形成速率和形态的关键影响因素。
