| 摘 要： | 研究了超声条件下四氯化碳与甲基橙混合水溶液的协同降解规律.超声能够使水中的四氯化碳迅速降解,而甲基橙水溶液的单独超声降解效果极差,但四氯化碳存在时其超声降解效率能够得到极大地增强.结果表明,使用40kHz,0.272 W·cm-2超声作用6 min,四氯化碳饱和水溶液(5.23 mmol·L-1)降解率达到91.83%...

| Abstract: | The synergistic effect of ultrasonic decomposition of CCl4 and methyl orange(MO) simulated wastewater was investigated.The sonochemical degradation of CCl4 in water is very rapid,while the ultrasonic degradation of MO aqueous solution is very poor.But the ultrasonic degradation of MO can be drastically enhanced in the presence of CCl4.After irradiation for 6 min by using 40 kHz,0.272 W cm 2 ultrasound,the degradation ratios of CCl4 saturated aqueous solution(5.23 mmol L 1) and 24 mg L 1 MO are 91.83% and 0.... |
