Abstract

The kinetics of the oxidation of endocrine disruptor nonylphenol (NP) by potassium ferrate(VI) (K2FeO4) in water as a function of pH 8.0–10.9 at 25°C is presented. The observed second-order rate constants, kobs, decrease with an increase in pH 269–32 M−1 s−1. The speciation of Fe(VI) (HFeO 4 and FeO 4 2− ) and NP (NP–OH and NP–O) species was used to explain the pH dependence of the kobs values. At a dose of 10 mg L−1 (50 μM) K2FeO4, the half-life for the removal of NP by Fe(VI), under water treatment conditions, is less than 1 min.
