摘    要:以苯胺溶液为研究对象,考察了超声时间、苯胺溶液浓度、pH值、氧化剂H2O2的浓度等因素对其超声降解率的影响。实验结果表明:超声时间越长,苯胺降解率越大;苯胺初始浓度与其降解率基本成线性关系;随着pH值的增大,降解率先增大后减少,在pH=7.3附近降解率最高;对于32.23mg/L的苯胺溶液,H2O2的浓度由0增加到1.6mg/mL,降解率从6.02%增加到93%,再增大H2O2的浓度,对其降解率影响不大。

关 键 词:实验研究  超声波  降解  苯胺  废水处理

Abstract:The effects of ultrasonic irradiation time, concentration of aniline solution, pH and condntration of addtive H 2O 2 on the degradation efficiency of aniline were studied. The results showed that the longer sonication time was relatied, the greater degradation efficiency was gained; the degradation efficiency of aniline solution increased with the increasing of the original solution concentration linearly; the degradation of aniline increased at first, then decreased with the increasing of pH ; the degradation of aniline reached to the highest at pH=7 3; when the concentration of H 2O 2 increased from 0 to 1 60?mg/mL, the degradation efficiency of aniline solution (the initial concentration is 32 23?mg/L) increased from 6 02% to 93%, then kept constant even the concentration of H 2O 2 increased continually.
Keywords:ultrasonic  wave  degradation  aniline
