Abstract This study investigates influence factors and thermal degradation of decabromodiphenyl ether(BDE-209) under the temperature range of 200~300℃. The results indicated that pyrolysis of BDE-209 was affected by temperature, time and common metal salts which were produced during the manufacturing and processing of printed circuit boards, such as copper nitrate, ferric chloride, aluminum chloride and zinc chloride. Pyrolysis of BDE-209 could be accelerated with the rise of temperature and extension of pyrolysis time. Results showed a greater impact of temperature on pyrolysis than that of time. A significant acceleration of pyrolysis was detected with copper nitrate, ferric chloride and aluminum chloride with degradation rates of BDE-209 in copper nitrate >ferric chloride >aluminum chloride. Pyrolysis of BDE-209 was inhibited with the presence of zinc chloride. Acceleration of aluminum chloride and inhibition of zinc chloride were weakened with the increase of temperature. This research results can provide a scientific basis for further study on the release and degradation of BDE-209 from electronic waste during the thermal treatment.
