摘要
研究了在微波/H2O2辐射下苯酚溶液降解率,考察了影响微波/H2O2辐射降解苯酚溶液的各种因素。试验结果表明:苯酚降解率与溶液初始浓度、pH值、微波辐射时间和微波辐射温度等因素有关。随着微波温度的增加苯酚降解率呈线性增加。且初始溶液浓度愈高,苯酚降解量愈高。微波辐射时间愈长,苯酚降解率愈高。微波对苯酚的降解过程符合表观一级反应动力学规律,其反应速率常数为0.013 84 min-1,活化能为10.56 kJ/mol。
Phenol degradation rate by microwave radiation/H2O2,and various factors affecting degradation efficiency were investigated.According to the result,the degradation rate is determined by initial concentration,pH,radiation time and temperature,etc.As the temperature of microwave or radiation time increases,there is a linear increase in degradation rate.Similarly,the amount of phenol degradation increases at a higher initial concentration.The degradation process corresponds with first order reaction,whose reaction rate constant is 0.013 84 min-1,activation energy is 10.56 kJ/mol.
