Comparativperformance of Potassium Ferrate(vi) in Drinking Water and Sewage Treatment
نویسندگان
چکیده
The use of potassium ferrate(VI) as an alternative water treatment chemical for both drinking water and sewage treatment has been studied and is reported in this paper. The performance of potassium ferrate(VI) was evaluated in comparison with sodium hypochlorite (NaOCl) and NaOCl plus ferric sulphate (FS) and aluminium sulphate (AS). The effects of the dosages of ferrate(VI), NaOCl and FS/AS and sample pH values on the treatment performance were investigated.

متن کاملKinetics of the oxidation of endocrine disruptor nonylphenol by ferrate(VI)
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 dos...
متن کاملDegradation 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...
