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...
متن کاملPhotocatalytic degradation of Congo Red dye by using nano ZnO and Ni-Co-ZnO nanocomposites
Photocatalysis has attracted significant attention as a potential issue for the degradation of toxic organic pollutants such as Congo Red. In this research spherical Pure ZnO nano particles and Ni-Co-ZnO nano composites (Zn0.95Ni0.04Co0.01O, Zn0.95Ni0.025Co0.025O and Zn0.95Ni0.01Co0.04O) have been synthesized by precipitation method. X- ray diffraction, Fourier transform Infra Red ,field emis...
متن کاملPhotocatalytic degradation of methyl orange and Congo red using C,N,S-tridoped SnO2 nanoparticles
In this study, the photocatalytic degradation of methyl orange and Congo red dye was investigated inaqueous solution using C,N,S-tridoped SnO2 nanoparticles as a nano photocatalyst. The degradationwas carried out under different conditions including the photocatalyst amount, initial concentrationand pH of the solution. The results indicated that the degradation of methyl orange and Congo redwas...

So, color wastewaters decomposition plan are...
متن کاملPhotocatalytic decolorization of methyl orange dye using nano-photocatalysts
Environmental contamination, which is growing around the world, is a serious problem can not to be neglected. Among all contaminations, water pollution is a major problem. Azo dyes are one of the largest groups of pollutants found in the drinking water, coming from, and the food and textile industries. TiO2/Fe3O4 and TiO2/Fe2O3 nanocomposites with various ratios were synthesized by an ultrasoni...
