Photocatalytic Degradation of Textile Dyeing Wastewater Using Titanium Dioxide and Zinc Oxide

Textile Dyeing Wastewater Treatment

Textile industry can be classified into three categories viz., cotton, woolen, and synthetic fibers depending upon the used raw materials. The cotton textile industry is one of the oldest industries in China. The textile dyeing industry consumes large quantities of water and produces large volumes of wastewater from different steps in the dyeing and finishing processes. Wastewater from printing...

Photocatalytic degradation of textile dyes by hydrogel supported titanium dioxide nanoparticles

Background: Textile industry has been condemned as one of the world’s worst offenders in terms of pollution because 10-15% of all the dyes used in the industry are lost within wastewater during processing. The presence of even very low concentrations of dyes in effluent is highly visible and degradation products of these textile dyes are often carcinogenic. Owing to the complex nature of synthe...

Photocatalytic Degradation of Acid Yellow 36 Using Titanium Dioxide Nanocomposites Doped by Zirconium

Introduction: In this research, TiO2-Zr nano-photocatalyst was firstly developed with the aim of improving the photocatalytic activity of titanium dioxide via sol-gel method. The recovery of catalysts in acidic, alkaline and thermal conditions was also studied. Method: This research was done on a laboratory scale. The structures and properties were recognized with (BET), (FT-IR), (FE-SEM), and...

Titanium dioxide mediated photocatalytic degradation of malathion in aqueous phase

The photocatalytic degradation of technical grade pesticide ‘malathion’ has been studied in aqueous suspensions of TiO2. The main aim of using this process is to degrade the toxic complex structure of the pesticide to harmless products by treating the sample in the UV-reactor. The COD measurements are carried out in order to study the percentage mineralization and degradation is studied under d...
