Decolorization of Mordant Red 15 Dye in Water by Potassium Ferrate (VI)

Abstract:

Decolorization of the Mordant red 15 dye in water was investigated in laboratory-scale experiments using potassium ferrate (VI). The effect of corresponding parameters such as reaction time, concentration of potassium ferrate, pH values and the addition of H₂O₂ were considered in the experiments. The results indicated that about 78% dye decolorization was obtained in less than 30 min under optimum conditions. The pH values and concentration of ferrate (VI) were correlated with color removal rate of Mordant red 15 dye. The optimum pH value and ferrate (VI) concentration are 5 and 450 mg/L, respectively. Addition of H₂O₂ could initiate the Fenton reaction and result in 84.46% decolorization of dye in 30 min. Due to high ability of oxidizing and flocculation, potassium ferrate (VI) is an effect way for treatment of dyes in water.
