Experimental Study on Treatment of Reactive Gaudy Red X-3B Dye Wastewater by Immobilized Fe³⁺- TiO₂ Photocatalytic Oxidation

Abstract:

The effect and law of photocatalytic degradation of reactive gaudy red X-3B dye were investigate and the applied process parameters were determined.Using self-synthesized immobilized Fe³⁺- TiO₂ photocatalyst,self-made catalytic oxidation reactor was made to research on reactive gaudy red X-3B dye wastewater by using light source of 20W UV sterilization light.The effects of immobilized Fe³⁺- TiO₂ catalyst content、pH value、Fe³⁺doping content and adding trace H₂O₂ on photocatalytic degradation were discussed.The experimental result show that reactive gaudy red X-3B dye wastewater decolorization rate and the removal rate of COD are more than 99% and 90% when the initial reactive gaudy red X-3B dye wastewater concentration was 50mg/L,pH value was 3,input amount of catalyst was 10g/L,Fe³⁺doping content was 0.5% and the dosage of H₂O₂ was 0.6mL/L(3%).Immobilized Fe³⁺- TiO₂ photocatalyst can remove the color and persistent organic pollutants in reactive gaudy red X-3B dye wastewater effectively.
