  Photochemical transformations of tetrabromobisphenol A and related phenols in water

  摘要：

  A method was developed for studies of the phototransformation at UV irradiation of aqueous solutions of tetrabromobisphenol A (TBBPA), tribromobisphenol A (TriBBPA), tetrachlorobisphenol A (TCBPA), 2,4-dichlorophenol at various pHs as well as 2-chlorophenol, 2-bromophenol, 3,4-dichlorophenol and bisphenol A at pH 11. The absorbance spectra of the compounds and the emission spectra of the light-source were determined and used to calculate disappearance quantum yields of the photochemical reactions that were taking place. No major differences between the disappearance quantum yields of TBBPA and TCBPA were observed at pH 10, while the disappearance quantum yield of TriBBPA was approximately two times higher. The rate of decomposition of TBBPA was six times higher at pH 8 than at pH 6. Identification of the degradation products of TBBPA and TriBBPA, by GC-MS analysis and by comparison to synthesised reference compounds, indicated that TBBPA and TriBBPA decompose via different mechanisms. Three isopropylphenol derivatives; 4-isopropyl-2,6-dibromophenol, 4-isopropylene-2,6-dibromophenol and 4-(2-hydroxyisopropyl)-2,6-dibromophenol, were identified as major degradation products of TBBPA while the major degradation product of TriBBPA was tentatively identified as 2-(2,4-cyclopentadienyl)-2-(3,5-dibromo-4-hydroxyphenyl)propane.

  have been conducted worldwide to investigate flame-retardant sources, environmental distribution, living organisms’ exposure, and toxicity. The presented studies include the degradation of 4,4′-isopropylidenebis(2,6-dibromophenol) (TBBPA) by ozonolysis and photocatalysis. In the photocatalytic process, nano- and micro-magnetite (n-Fe3O4 and μ-Fe3O4) are used as a catalyst. Monitoring of TBBPA decay

  阻燃剂引起了越来越多的环境问题。最近，全球范围内开展了越来越多的研究来调查阻燃剂的来源、环境分布、生物体的暴露和毒性。所提出的研究包括通过臭氧分解和光催化降解 4,4'-异亚丙基双(2,6-二溴苯酚) (TBBPA)。在光催化过程中，纳米和微米磁铁矿（n-Fe 3 O 4和μ-Fe 3 O 4）用作催化剂。监测光催化和臭氧分解中的 TBBPA 衰减表明光催化更有效。在光催化中，TBBPA 可在 10 分钟内显着去除（约90%），而对于臭氧化，在 70 分钟内观察到类似的效果。为了确定 TBBPA 降解 COD 和 TOC 浓度的最佳方法，对去除量进行了检查。μ-Fe 3 O 4的光催化氧化态最高，而n-Fe 3 O 4和臭氧分解的COD/TOC比值较低。急性毒性结果表明，TBBPA及其降解产物对Artemia franciscana和Thamnocephalus platyurus的毒性存在显着差异。欧共体50值表明
