摘要
研究了苯酚水溶液在超声波/过氧化氢(US/H2O2)复合氧化工艺条件下的降解效果及机理.详细讨论了H2O2体积质量、苯酚初始体积质量、溶液初始pH和外加Fe2+等因素对US/H2O2工艺氧化降解苯酚的影响.结果表明:在单独的超声波辐照或者过氧化氢氧化下苯酚去除率很小,而在组合氧化过程US/H2O2工艺中有显著的提高;苯酚降解的拟一级动力学速率常数增强因子可达到6.904,存在明显的协同效应.
Phenol in aqueous solution was treated by US (Ultrasound)/H_2O_2 (Hydrogen Peroxide) combination process. The effects of factors such as concentration of H_2O_2, initial pH, initial phenol concentration and the amount of Fe^(2+) were studied. Experimental results showed that the removal rate of phenol was low when single ultrasound irradiation process or H_2O_2 oxidation was used. US/H_2O_2 combination process was favorable for enhancing the removal rate of phenol, with the enhancement factor of the first-order kinetics constant being around 6.904. The synergetic effect of US/H_2O_2 combination process was obvious.
