The oxidative removal of a diverse group of trace organic contaminants from surface water and wastewater was evaluated using ozone (O 3 ) and O 3 combined with hydrogen peroxide (O 3 /H 2 O 2 ). Target compounds included estrogenic and androgenic steroids, pharmaceuticals, pesticides, and industrial chemicals. Bench-and pilot-scale experiments were conducted with surface water spiked with the target compounds and wastewater effluent containing ambient concentrations of target compounds. Full-scale water treatment plants were sampled before and after ozonation to determine if bench-and pilot-scale results accurately predict full-scale removal. In both drinking water and wastewater experiments, the majority of target compounds were removed by greater than 90% at O 3 exposures commonly used for disinfection. Atrazine, iopromide, meprobamate, and tris-chloroethylphosphate (TCEP) were the most recalcitrant compounds to oxidize using O 3 , with removals generally less than 50%. The addition of H 2 O 2 for advanced oxidation was of little benefit for contaminant removal as compared to O 3 alone. O 3 /H 2 O 2 provided a marginal increase in the removal of dilantin, diazepam, DEET, iopromide, and meprobamate, while decreasing the removal efficacy of pentoxifylline, caffeine, testosterone, progesterone, and androstenedione. In wastewater experiments, O 3 and O 3 /H 2 O 2 were shown to remove in vitro estrogenicity. Collectively, these data provide evidence that O 3 is a highly effective oxidant for removing the majority of trace organic contaminants from water.

“…Investigations into the removal of bisphenol A from aqueous environments have studied the use of carbon adsorption [11], electrochemical treatments [12], oxidative coupling mediated by horseradish peroxidase [13], as well as photocatalytic oxidation [14][15][16], sonochemical oxidation [17], ozone oxidation [18], and enzymatic oxidation [19]. While each process offers some degree of effectiveness in the breakdown or removal of BPA in aqueous solutions, advanced oxidation processes (AOPs) such as radiolysis, photocatalysis, sonolysis, and UV-peroxide are often considered the best choice for the removal of recalcitrant compounds.…”

Bisphenol A reactions with hydroxyl radicals: diverse pathways determined between deionized water and tertiary treated wastewater solutions

2009

The oxidative reactions of bisphenol A (BPA) with radiolytically generated hydroxyl radicals were studied in both deionized water and tertiary treated wastewaters. In deionized water, bisphenol A reacts with the hydroxyl radical by addition to the aromatic ring, k = 6.9 9 10 9 (±0.2) M -1 s -1 , to eventually form the prominent, long-lived, hydroxylated intermediate product. In contrast, in tertiary treated water solutions, although the initial hydroxyl radical addition reaction occurs, the hydroxylation is averted, and a different mechanistic pathway ensues. The removal constant for the hydroxyl radical reaction with BPA is 0.45 ± 0.04 lmol/kGy, corresponding to an overall degradation efficiency of 76%.

Abstract: The incorrect value of k O3/Phenol was given. The correct value is kO3/Phenol ) 1.3 (( 0.2) × 10 3 M -1 s -1 (ref 36 cited in our article). This does not change our results, which were obtained using the correct value of kO3/Phenol.
