Abstract

In this study, ozone (O₃) was applied to oxidize nonylphenol (NP) and nonylphnol ethoxylates (NPEOs). Both oxidation performance and kinetics were evaluated under different operating conditions created by varying O ₃ doses,solution pHs or molar ratios of H₂O ₂/O₃.This study demonstrates that at pH 7, more than 90% NP (initial NP concentration: 0.51 mg/L) can be removed by 4 mg/L O₃. In all pH range (5-9), NP was also effectively oxidized. However, the amount of NP destructed by O₃ in the ID phase (instantaneous O₃ demand during 30 sec) was more significant at higher pH. The NP destruction in the ID_30sec phase was also significantly increased when H ₂O₂ was applied along with O₃. O₃ was also found to be very effective in oxidizing NPEOs.
