摘要
应用超声波-零价铁(US-Fe0)协同降解水中有机染料直接湖蓝5B,考察了超声波—零价铁的协同效应,研究了溶液初始pH值、超声功率,零价铁投加量等因素对直接湖蓝5B降解效果的影响。结果表明降低反应溶液的pH值有利于提高降解率;在实验的投加范围内,零价铁投加量越多,降解率越高;而超声波功率对降解率的影响不很明显。
The degradation of direct sky blue 5B in aqueous solution by using Supersonic wave and Fe0 was studied and the effects of operating parameters such as Fe0addition,the Supersonic power and medium pH was investigated.The results showed that the degradation of direct sky blue 5B by ultrasound was obviously enhanced by addition of Fe0.It was found that the degradation of direct sky blue 5B were increased with increasing the Fe0 addition,and the degradation rate of direct sky blue 5B was decreased with increasing the medium pH of the dye solution.The effect of ultrasonic power was not obvious.
