摘    要:采用固载Fe(Ⅲ)-H2O2-UV降解2,4-二氯苯酚,探讨了光照时间、pH值、H2O2浓度、载铁树脂用量以及2,4-二氯苯酚初始浓度等因素对降解率的影响。结果表明,固载Fe3+-H2O2-UV降解2,4-二氯苯酚的适宜工艺条件为:2,4-二氯苯酚初始浓度为8μg/mL,pH>2,H2O2浓度为0.003 mol/L,载铁树脂用量0.02~0.1 g,紫外光照时间达120 min。在此条件下,2,4-二氯苯酚降解率可达94.8%。

关 键 词:载铁树脂  H2O2  2  4-二氯苯酚  紫外光  降解

Abstract:Degradating 2,4-dichlorophenol with solid Fe(III)-H2O2-UV.Effect of the time of illumination,pH value,the concentration of H2O2,the amount of loading iron resin,and the initial concentration of 2,4-dichlorophenol of the degradation were discussed.The results indicated that the optimum condition are as follows:the time of ultraviolet illumination 120 min,pH >2,the initial concentration of 2,4-dichlorophenol is 8 μg/mL,proper H2O2 concentration is 0.003 mol/L.Amount of iron be loaded is 0.02~0.1 g.In this condition,2,4-dichlorophenol degradation rate reach 94.8%.
Keywords:loading iron resin  H2O2  2  4-dichlorophenol  ultraviolet  degradation
