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, k obs, decrease with an increase in pH 269–32 M−1 s−1. The speciation of Fe(VI) (HFeO −4 and FeO 2−4 ) and NP (NP–OH and NP–O−) species was used to explain the pH dependence of the k obs 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.
