Photocatalytic decolorization of methyl orange dye using nano-photocatalysts
Environmental contamination, which is growing around the world, is a serious problem can not to be neglected. Among all contaminations, water pollution is a major problem. Azo dyes are one of the largest groups of pollutants found in the drinking water, coming from, and the food and textile industries. TiO2/Fe3O4 and TiO2/Fe2O3 nanocomposites with various ratios were synthesized by an ultrasoni...
متن کاملPhotocatalytic Decolorization of Methyl Orange by Silica-Supported TiO2 Composites
Immobilization of TiO2 on silica gel has been proposed to enable easy separation of the catalyst in aqueous systems after photocatalytic reaction. Our simple synthesizing method reduces production cost, and the photocatalyst could find economical application in wastewater treatment. Silica-supported TiO2 composites were prepared by molten salt method at 500, 600 and 700 °C for 60 min. The obtai...
متن کاملPhotocatalytic Decolorization of Methyl Orange Solution with Phosphotungstic Acid
Photocatalytic decolorization of Methyl Orange (MO) solution has been studied using phosphotungstic acid (HPA) as photocatalyst. The decolorization reaction of MO solution is photocatalysis. The paper reveals that the optimal loading of photocatalyst for decolorization of MO solution (10 mg/L) is 0.6 g/L. The results show that the photocatalytic decolorization reaction of MO with HPA in a h...
