微波辅助H_2O_2降解水中苯酚的研究

The Study on Microwave Assisted H_2O_2 Degradation of Phenol in Water

对微波辅助H2O2降解水中苯酚进行研究,考察了不同因素对苯酚降解效果的影响.结果表明:微波辅助H2O2降解水中苯酚最佳降解条件为:对于100 mL浓度为50 mg·L-1的苯酚溶液,加入质量浓度为6%的H2O2溶液8.0 mL,在室温、微波功率500 W下,微波作用45 min,苯酚降解率可达88.76%.实验同时表明:微波与H2O2在降解苯酚时存在明显的协同效应.

Microwave assisted H2 O2 degradation of phenol in water was studied. Different factors associated with the effect of degradation were investigated. Results indicated that the optimal conditions for microwave assisted H2 O2 degradation of phenol in water were as follows：for the 100 mL phenol solution with concentration 50 mg·L - 1 , adding 8. 0 mL H2 O2 solution（6% ）,microwave power 500 W,at room temperature,the degradation ratio was up to 88. 76% after 45 min. Meanwhile,the experimental results showed that the microwave and H2 O2 have obvious syn-ergetic effect for the degradation of phenol solution.
