摘要：选取间苯二酚为代表,研究了超声波对二元酚水溶液的降解能力。考察了超声输出功率,溶液pH值等工艺条件对降解效果的影响。实验结果表明,超声波可以有效地降解间苯二酚水溶液,超声最佳输出功率为200 W,偏酸性溶液(pH=4)有利于降解的进行。同时还探讨了H2O2-超声联合作用对间苯二酚降解的影响。实验数据证明,H2O2对超声波降解间苯二酚水溶液具有明显的促进作用,溶液体系中存在少量双氧水时,超声作用8 h,间苯二酚的降解率达到98.7%。
The degradation effect of resorcin aqueous solution by ultrasound technology and the major affecting factors such as the sound power, pH value of the solution were studied in this paper. The ultrasound could degradate the resorcin aqueous solution effectively. The excellent degradation rate was obtained while the sound power was 200 W and the pH value of the solution was 4. At the same time, the degradation of resorcin aqueous solution by ultrasound-H2O2 technology was investigated. The results showed that ultrasound-H2O2 technology was superior to ultrasound irradiation alone in degrading resorcin. After 8 h,the degradation rate of resorcin reached 98.7% ,with a few H2O2 in the system.
