Abstract
Official abstract text for this publication.
Disclosed are a method and apparatus for decolorization of reactive anthraquinone dye-containing wastewater using photocatalytic oxidation, which include inducing high-efficiency photocatalytic oxidation under a controlled salt concentration and pH of wastewater to perform effective decolorization of reactive anthraquinone dye-containing wastewater. The method for decolorization of reactive anthraquinone dye-containing wastewater using photocatalytic oxidation, includes: introducing a photocatalyst and salt into reactive anthraquinone dye-containing wastewater and adjusting pH of the wastewater to a level higher than neutral pH; and irradiating UV to the photocatalyst to carry out cleavage of the reactive anthraquinone dyes through photocatalytic oxidation, thereby accomplishing decolorization of wastewater.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for decolorization of reactive anthraquinone dye-containing wastewater using photocatalytic oxidation, comprising: introducing a photocatalyst and salt into reactive anthraquinone dye-containing wastewater wherein the salt is at least one selected from a group consisting of NaCl, Na2SO4, KNO3, CuSO4, NH4Cl, CH3COONa and combinations thereof, and the wastewater is maintained at a salt concentration of 50-100 g/L; and irradiating UV to the photocata…
