dc.description.abstract探究了针铁矿催化转化溴酚(2,4-dbP或2,4,6-TbP)生成羟基化多溴联苯醚(HO-PbdES)和溴代二噁英(Pbdd/fS)的可能性.结果表明,针铁矿可以在常温和干反应条件下有效地催化转化溴酚化合物生成HO-PbdES和Pbdd/fS.反应16 d,97.3%的2,4-dbP被针铁矿氧化转化,其中2.4%被转化为2′-OH-bdE-68,2.8%被转化为2,2′-OH-bb-80,0.2%被转化1,3,8-Trbdd,0.4%被转化为2,4,6,8-TEbdf.同样的反应时间内,98.7%的2,4,6-TbP被针铁矿氧化转化,反应产物可能为2′-OH-bdE-121、4′-OH-bdE-121、1,3,6,8-TEbdd和1,3,7,9-TEbdd.根据检测到的产物,提出了针铁矿氧化转化溴酚的可能途径.
dc.description.abstractThe formation of hydroxylated polybrominated diphenyl ethers( HO-PBDEs) and brominated dibenzop-dioxins, dibenzofurans( PBDD/ Fs) from goethite-catalyzed oxidation of bromophenols( BPs, e.g., 2, 4-DBP and 2, 4, 6-TBP) was investigated.Results showed that goethite readily catalyzed the conversion of 2,4-DBP and 2,4,6-TBP to HO-PBDEs and PBDD/ Fs under dry conditions and at ambient temperature.In 16 d, 97.3% of 2,4-DBP was converted and the yields of 2′-OH-BDE-68, 2,2′-OH-BB-80, 1,3,8-TrBDD and 2,4,6,8-TeBDF were 2.4%, 2.8%,0.2% and 0.4%, respectively.Similarly, 98.7% of 2,4,6-TBP was transformed and the possible reaction products were 2′-OH-BDE-121, 4′-OH-BDE-121, 1,3,6,8-TeBDD and 1,3,7,9-TeBDD.The possible formation pathways for the goethite-catalyzed oxidation of bromophenols were proposed.
