Abstract

Public concerns on nonylphenol and its ethoxylates (NP and NPEOs) are growing because they are frequently detected in the aquatic environment. Since these compounds cannot be completely degraded by microbes, chemical oxidation has been applied to degrade NPEOs. In this study, ferrate(VI) was used to oxidize NP and its oxidation kinetics was evaluated. The effect of H₂O₂ presence on the NP oxidation by ferrate(VI) was also evaluated. In general, NP was more effectively oxidized at higher pH than at neutral medium. However, the initial destruction of NP by ferrate(VI) was more significant at low pH. The addition of H₂O₂ did not have much impact on the NP oxidation, which needs further investigation. As for the kinetics of the NP oxidation by ferrate(VI), the second-order rate constant was determined as k_app=3.9×10¹/M/s at pH 8.
