摘要
研究紫外/臭氧(UV/O3)高级氧化法降解水中布洛芬的效果,并与单独UV法、O3法的实验结果进行对比分析。结果表明:在纯水中,UV/O3法降解布洛芬的效果显著,10 min反应条件下,分别比O3法和UV法降解效率提升近24%和85%。3种处理方法中,布洛芬初始浓度的升高均对其降解有抑制作用,且降解过程均符合伪一级动力学方程。碱性环境更利于UV/O3和O3对布洛芬的降解,UV/O3可以将布洛芬在130 min内矿化超过80%,动力学分析发现,UV/O3矿化布洛芬的过程符合伪零级动力学方程。
The degradation efficiency of ibuprofen in water treated by ultraviolet/ozone(UV/O3)advanced oxidation process was investigated,and the results were compared with those obtained from individual UV and O3 process.The results showed that UV/O3 had significant degradation for ibuprofen in pure water,and its efficiency increased by 24%and 85%respectively compared with O3 and UV process under 10 min reaction conditions.Among these three treat-ment methods,the increase of the initial concentration of ibuprofen inhibited its degradation,and the degradation of ibuprofen conformed to the pseudo first-order kinetic equation.The alkaline condition was more favorable for the de-gradation of ibuprofen by UV/O3 and O3,UV/O3 could mineralize ibuprofen over 80%within 130 min.The kinetic an-alysis found that the mineralization of ibuprofen by UV/O3 conformed to the pseudo zero-order kinetic equation.
