ACID ORANGE 52 DYE DEGRADATION BY ELECTROCATALYTIC PLUS PHOTOCATALYTIC TECHNIQUE AND INTERMEDIATES DETECTION

Photocatalytic degradation of textile dye direct orange 26 by using CoFe2O4/Ag2O

The magnetic and recyclable nanoparticles of CoFe2O4 were synthesized by a reverse co-precipitation process. Sonication was used to couple the CoFe2O4 surface with Ag2O. The characteristics and optical properties of the catalyst were studied by powder X-ray diffraction, UV–visible reflectance spectroscopy and scanning electron microscopy analyses. Pure CoFe2O4 and CoFe2O4/Ag2O were utilized to ...

Microbial Degradation and Decolorization of Acid Orange Dye by Anaerobic /Aerobic Sequential Process

This study investigates the anaerobic treatability of Acid orange dye in an anaerobic/aerobic sequential process. Laboratory scale anaerobic baffled reactor and fixed activated sludge reactor were operated at different organic loadings and hydraulic retention times. The effects of shock dye concentration on the chemical oxygen demand and color removal efficiencies were investigated in the anaer...

Photocatalytic degradation of methyl red dye

Introduction Most dyes used in the pigmentation of textiles, paper, leather, ceramics, cosmetics, inks and food-processing products are derived from azo dyes, which are characterised by the presence of one or more azo groups (-N=N-) in their structure. Approximately 15% of the dyes produced worldwide are lost within waste water during synthesis and processing. This waste represents a great haza...
