Photoreductive debromination of decabromodiphenyl ether by pyruvate

摘要：

　　Polybrominated diphenyl ethers (PBDEs) have aroused global environmental concerns because of their toxicity and ubiquitousness in the biological and environmental systems.Here,we report that decabromodiphenyl ether (BDE209) undergoes efficient reductive debromination reactions by pyruvate in UV irradiation (>360nm).The photoreductive degradation kinetics of BDE209 has been further investigated under different reaction conditions.The debromination reactions occur in a stepwise process,producing a series of lower brominated PBDE congeners.The debromination shows unconspicuous position-selective.The possible photoreductive mechanism was proposed by kinetic isotope effect (KIE).This study not only provides a potential application of removal of PBDEs contaminations but also provide useful information for the fate of PBDEs in environment.
