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 25C is presented. The observed second-order rate constants, kobs, decrease with an increase in pH 269-32 M-1s-1. The speciation of Fe(VI) (HFeO4- and FeO42- 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 (50M) K2FeO4, the half-life for the removal of NP by Fe(VI), under water treatment conditions, is less than 1 min. Springer-Verlag 2008.
