• 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=73附近降解率最高;对于32.23mgL的苯胺溶液, H₂O₂的浓度由0增加到1.6mgmL, 降解率从60.2%增加到93%, 再增大H₂O_2<

• Abstract：The effects of ultrasonic irradiation time, concentration of aniline solution, pH and condntration of addtive H₂O₂ 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 H₂O₂ increased from 0 to 1.60mg/mL, the degradation efficiency of aniline solution (the initial concentration is 32.23mg/L) increased from 6.02% to 93%, then kept constant even the concentration of H₂O₂ increased continually.
