Ozonation and peroxone oxidation of benzophenone-3 in water: Effect of operational parameters and identification of intermediate products

► Ozonation shows to be a promising technology for the elimination of BP3. ► New data are obtained on the effect of process parameters on BP3 removal. ► Conditions favoring hydroxyl radical formation accelerate the degradation process. ► The reactivity is higher through radicalar pathways compared to direct ozonation. ► Seven major transformation products of BP3, including BP1 and DHMB, are identified.
