| 摘 要： | 研究了微波/过氧化氢（MW/H2O2）系统催化氧化降解苯酚的动力学。结果表明，在单独的微波辐射（MW）或者过氧化氢（H2O2）氧化条件下苯酚去除率很小，而在MW/H2O2系统中有显著的提高，表明协同效应存在。另外，在三种工艺条件下苯酚的降解均符合表观一级动力学。在MW/H2O2系统中苯酚去除的速率常数增强因子可达到5.98，根据此系统中存在MW、H2O2和羟基自由基（·OH）三部分协同作用的降解机理，推导出了简化的苯酚降解动力学模型，较好的反应过氧化氢浓度过量条件下的苯酚降解。

| Abstract: | The synergetic kinetics of phenol degradation in water by using microwave/H2O2(MW/H2O2)system was studied.It was found that phenol degradation followed pseudo-first order reaction and was significantly enhanced and the rate constant enhancement was about 5.98 in the combined MW/H2O2 system.This fact indicated that there existed synergetic effects in the MW/H2O2 process.A simplified mechanistic model for phenol degradation was proposed to account for the combined contribution of MW radiation,H2O2 oxidation and hydroxyl radical,and was well suitable for the phenol degradation in the presence of superfluous H2O2. |
