| 摘 要： | 研究了功率超声对有毒蓝藻的主要次级代谢物藻毒素的降解作用,以及超声参数等条件对降解效果的影响.结果表明微囊藻毒素在超声场中具有很好的降解效果,实验条件下,频率为150 kHz的超声对藻毒素的降解效果最好,其功率为40 W时,作用20 min后藻毒素的降解率可达到70%以上.同时紫外光辐照可以有效地强化超声对藻毒素的降解.

| Abstract: | Sonochemical degradation of microcystins(MC) produced by microcystis in water and the influence of various ultrasonic parameters were studied.The results show that microcystins could be effectively degraded in ultrasonic fields.150 kHz is the best ultrasound frequency for microcystins degradation,and the removal ratio of microcystins reached 70% after 20 min ultrasonic irradiation at 150 kHz and 40 W.Furthermore,ultraviolet irradiation strengthened the ultrasonic degradation of microcystins. |
