超声波降解苯酚溶液的研究

Degradation of Phenol Aqueous Solution with Ultrasonic

以20mg/L的苯酚为研究对象,在超声波槽中对超声波作用于苯酚的降解效率和降解规律进行了初步研究。实验表明:单一的超声波对苯酚的降解率是很低的,不超过6.3%;而在苯酚溶液中加入H2O2后,降解率提高了大约3倍;酸性条件利于苯酚的降解,而在碱性条件下苯酚几乎没有降解。

Degradation efficiency and rule of 20% phenol by ultrasonic was studied primarily.the results of the experiment showed that the degradation ratio with ultrosound was too low, and no more than (6.3%),But the degradation ratio was promoted nearly three times when H_2O_2 was added into the phenol aqueous solution. Phenol was easy to be degraded in the acid condition,but difficult in the alkaline condition.
