Abstract
Azo-dye wastewater is hard to degrade due to its high content of organic compounds,its complexity of the components and high chroma.And its treatment method has been concerned extensively.TiO2 is a highly efficient catalyst which can be used in the photocatalytic degradation of organic pollutants owing to its high light stability and high reaction activity.This paper reviewed the research methods of azo-dyes wastewater by photocatalytic oxidation with TiO2.
