Kinetics of the oxidation of endocrine disruptor nonylphenol by ferrate(VI)
نویسندگان
چکیده
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 s. The speciation of Fe(VI) (HFeO4 and FeO4 ) 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 lM) K2FeO4, the half-life for the removal of NP by Fe(VI), under water treatment conditions, is less than 1 min.

Degradation of endocrine disrupting chemicals in aqueous solution by interaction of photocatalytic oxidation and ferrate (VI) oxidation.
In this study, the degradation of bisphenol A in aqueous suspension by interaction of photocatalytic oxidation and ferrate(VI) oxidation was investigated under different conditions. The results indicate that the formation of Fe(V) and Fe(IV) is in the photocatalytic reduction of Fe(VI) by electron (ecb-) on the surface of TiO2. The oxidation efficiency of the photocatalytic oxidation in the pre...
متن کاملHydrogen sulfide and organic compounds removal in municipal wastewater using ferrate (VI) and ultraviolet radiation
Background: In this study, ferrate (VI) and ultraviolet (UV) radiation were employed to remove hydrogen sulfide from municipal wastewater resulting in a reduction in chemical oxygen demand (COD). Although ferrate (VI) and UV have been used individually for the removal of a few pollutants from urban and industrial wastewater, there exists no study to investigate the effectiveness of si...

Background; The aim of this study is to compare UV, ferrate (VI) and UV/ferrate (VI) methods for removal of hydrogen sulfide and chemical oxygen demand (COD) from municipal wastewater under a continuous condition. Methods; The experiment was divided into three parts: 1) pollutants removal by using ferrate (VI) alone; 2) pollutants removal using UV alone; 3) pollutants removal using a combina...
متن کاملFerrate(VI) oxidation of zinc-cyanide complex.
Zinc-cyanide complexes are found in gold mining effluents and in metal finishing rinse water. The effect of Zn(II) on the oxidation of cyanide by ferrate(VI) (Fe(VI)O(4)(2-), Fe(VI)) was thus investigated by studying the kinetics of the reaction of Fe(VI) with cyanide present in a potassium salt of a zinc cyanide complex (K(2)Zn(CN)(4)) and in a mixture of Zn(II) and cyanide solutions as a func...
