| 摘 要： | 选择了水溶液中亚甲蓝的声化学反应为研究体系，探讨了超声频率为19．6kHz时，亚甲蓝声化学反应的速率规律。实验结果表明，在实验条件下，亚甲蓝的声化学反应符合一级反应的动力学规律。亚甲蓝声化学反应速率常数随着超声功率的增加而增加，随着操作温度、亚甲蓝的初始浓度的增加而减小，催化剂Fe^2＋能增加亚甲蓝的声化学反应速率常数。pH值和曝气也能影响其声化学反应速率常数。

| Abstract: | Effects on the sonochemical reaction of methylene blue were studied under a 19.6kHz ultrasonic irradiation .The sonochemical reaction of methylene blue solution follows first-order kinetics. The reaction rate constant of methylene blue under the influence of ultrasonic power, initial concentration of methylene blue, operation temperature, Fe2+, aeration and pH of aqueous solution was investigated. The results show that when the ultrasonic power goes up, the reaction rate constant increases. The reaction rat... |
