摘    要:研究了用超声波技术降解水中对硝基苯酚.探讨了对硝基苯酚初始浓度、溶液初始pH值、声能密度及反应温度等因素对降解效果的影响及规律.实验发现,超声波降解水中对硝基苯酚的主要影响因素为反应物的初始浓度、溶液初始pH值、溶液声能密度及空化反应时间.在较低的pH值,较大超声声能密度的条件下,可有效降解低浓度对硝基苯酚废水.

关 键 词:超声  降解  对硝基苯酚  超声波  降解效果  对硝基苯酚  研究  Ultrasound  Aqueous  Solution  Degradation  硝基苯酚废水  初始浓度  条件  反应时间  空化  反应物  影响因素  发现  实验  规律  反应温度  声能密度  溶液

Abstract:The study on degradation of p-Nitrophenol in aqueous solution by ultrasound process has been given in this paper.The influence on degradation and laws by several factors ,which include the initial concentration,the initial pH,the energy density and the reaction temperature have been discussed. The results show that the initial concentration,the initial pH ,the energy density and the cavitation time are the main factors.Under the condition of lower pH value and higher energy density,the p-Nitrophenol wastewater of lower concentration can be degraded.
Keywords:Ultrasound  Degradation  p-Nitrophenol
