| 摘 要： | 文章研究了不同频率以及频率组合下正交和平行超声场降解氯苯溶液的效果,并对氯苯超声降解的动力学进行了分析。实验结果证明:其他条件相同的情况下,采用多频率组合超声场能有效的提高氯苯的降解效果;正交超声场降解效果优于平行超声场;多频超声场中氯苯降解过程符合虚拟一级反应特征,同时给出了3种频率及其频率组合条件下氯苯的超声降解动力学特征方程。

| Abstract: | Sonolysis of chlorobenzene in orthogonal or parallel ultrasonic field of different single frequency or combined frequencies were studied, and the kinetic rate of sonolysis of chlorobenzene was discussed. Results showed that the degradation efficiency of chlorobenzene at given time was improved by combined frequencies effectively, with the effect better in orthogonal ultrasonic field than in parallel ultrasonic field and the rate of degradation following a pseudo-first-order kinetic law. Furthermore, the kinetic equations for sonolysis of chlorobenzene at different single frequency and combined frequencies were also described. |
