| 摘 要： | 利用臭氧(O_3)以及臭氧联合过硫酸氢钾复合盐(O3/PMS)降解酮洛芬(KET)模拟废水,对比了两个体系中酮洛芬的降解效果以及初始pH值对酮洛芬降解的影响,并探究了降解机理.结果表明,酮洛芬的降解符合准一级动力学.PMS能促进臭氧氧化降解酮洛芬,在一定实验条件下其促进率为58.6%.初始pH值对两个体系降解酮洛芬均有明显的影响,pH值越高,降解效果越好.体系中同时存在O_3、·OH及SO_4~(·-),它们对酮洛芬降解的贡献率分别为4.35%、54.35%、41.30%.

| Abstract: | In this study, the simulated ketoprofen (KET) wastewater was oxidized by ozone (O3) and ozone combined with peroxymonosulfate (O3/PMS).The removal effect of KET in both systems and the influence of initial pH values, as well as the degradation mechanism were investigated.Results indicated that the degradation of KET followed pseudo-first order kinetics.PMS could dramatically accelerate the process of ozonation of KET with a promoting ratio of 58.61%.In addition, the degradation of KET in both systems were significantly affected by initial pH value and higher pH value would bring better degradation effect.It has been proven that both O3, ·OH and SO4·- simultaneously contributed to KET degradation in O3/PMS, with the contribution of 4.35%, 54.35% and 41.30%, respectively. |
