The paper studied the degradation effect and affecting factors of p-nitrophenol(P-NP) by ultra-sound technology,Fenton reagent technology and ultra-sound-Fenton reagent technology.

采用超声/Fenton联用技术对水中对硝基苯酚(P-NP)进行处理,探讨了单纯超声(US)、Fenton试剂法、US/Fenton试剂法联用对P-NP的处理效果和影响因素,结果表明,对于浓度为10mg/L的P-NP,当pH=3、H2O2与Fe2+投加量之比为10∶1、H2O2投加量为40mg/L时降解效果最好,通过动力学分析发现US/Fenton试剂法对P-NP的降解具有明显的协同效应。

Degradation of p-Nitrophenol in Water by Ultrasound/Fenton Reagent Method;

将超声波(US)/Fenton试剂法有机地结合起来,用于对硝基苯酚(p-NP)的降解实验,实验中发现US/Fenton试剂法降解p-NP具有明显的协同效应,结果优于Fenton试剂法与US法的简单加合。
