The effects of the co-existing compounds on the decomposition of micropollutants using the ozone/hydrogen peroxide process

摘要: The effect of co-existing compounds on the decompositions three target (i.e., 1,2,4-trichlorobenzene (TCB), 1,4-dioxane, and 17β-estradiol) using ozone/hydrogen peroxide (O3/H2O2) process was investigated. Their reactivities toward HO• are assumed to be order 109 /M · s. decomposition rate TCB much higher during O3/H2O2 than ozonation in presence bicarbonate ion, an inhibitor radical chain reactions. 17β-Estradiol, a highly reactive compound ozone, decomposed at lower ozone dose lowly humic acid. were significantly related treatment efficiency when their concentrations as TOC similar. acid, fulvic glucose, HO•, similar regardless compounds. On other hand, acetate oxalate ions, observed. Ozone required for inversely proportional concentration generated greatly scavengedby less affected by used effectively TCB.
