超声波-零价铁协同降解废水中活性深蓝M-2GE的研究

研究了超声波-零价铁对废水中活性深蓝M-2GE的协同降解，探讨了铁粉添加量、超声波功率、介质pH和染料的浓度等对活性深蓝M-2GE降解效率的影响。结果表明，零价铁的存在可显著提高废水中活性深蓝M-2GE的超声降解效率，其降解率随着铁粉添加量的增多而升高。介质pH对活性深蓝M-2GE的降解有显著影响，pH=3时降解率最高。另外增大超声功率有利于有机污染物的降解，有机染料的浓度越低，降解率越高。

Sonochemical degradation of reactive dark blue M-2GE with enhancement by zero-valent iron

The method of ultrasonic and Fe⁰ for the treatment of the degradation of reactive dark blue M-2GE in aqueous solution was studied and the effects of operating parameters such as Fe⁰ quantity, the ultrasonic power, medium pH and the concentration of the dye were investigated. The results showed that the degradation of reactive dark blue M-2GE was obviously enhanced by ultrasound/zero-valent iron process. It was found that the degradation of reactive dark blue M-2GE were increased with increasing the Fe⁰ quantity and ultrasonic power, and the degradation rate of reactive dark blue M-2GE was decreased with increasing the initial concentration of the dye. It was also found that the degradation of reactive dark blue M-2GE in aqueous solution was obviously affected by medium pH. The highest degradation rate was observed at pH 3.
