【摘要】 本实验研究了超声波、H₂O₂、可见光光敏化,以及它们联合使用降解有机溶剂中4,4′-DBB（4,4′-二溴联苯）。实验发现,超声、H₂O₂、可见光光敏化等对4,4′-DBB均有降解作用;在联合作用下,4,4′-DBB的降解率均有提高。实验结果表明,超声与H₂O₂联合作用于2mg/L的4,4′-DBB溶液时,降解率可由单独H₂O₂降解时的16.8%提高到42.1%;超声与可见光光敏化联合作用时,降解率由单独可见光光敏化降解时的22.9%提高到25.6%。更多还原

【Abstract】 In this experiment,the degradation of 4,4’-DBB（4,4’-Dibromobiphenyl） in organic agent by ultrasound、H₂O₂ and visible light photosentization has been studied.and also the combination.It was found that these technologies were useful to degrate 4,4’-DBB.The solution rate of 4,4’-DBB could be improved while the technologies were combined.The experiment as a result expressed that the combination of ultrasound and H₂O₂ could improve the solution rate of 2mg/L 4,4’-DBB to 42.6%while it was 16.8%when H₂O₂ was alone;the combination of ultrasound and visible light photosentization could improve the solutionrate to 25.6%while it was 22.9%when visible light photosentization was alone.更多还原
