Metal oxides play significant role in many fields of nanotechnology including nanocatalysis, sensing, supermagnetic properties, fuel cells, nanoenergy storage and conservation. Dyes are synthetic compounds which have wide range of application in textiles, paints etc., and the dye effluents from the dyeing industries cause water pollution. In this present study, ZnO photocatalyst have been synth...

This study describes the application of novel chemistry methods for the removal of dye by Nano structured titanium oxide (TiO2) photo catalysts. Such materials can be applied in the development of efficient photo catalytic systems for the treatment of water. Nano crystalline TiO2 was synthesized by Sol-Gel route using titanium tetraisopropoxide as a metal precursor. The catalysts were character...

BACKGROUND Organic dye pollution in water has become a major source of environmental pollution. Mn(III/IV) oxides have attracted a great deal of attention to remove organic dye pollutants due to their unique structures and physicochemical properties. Numerous studies have reported the removal of dye by various Mn(III/IV) oxides through catalytic degradation and adsorption. The crystalline struc...

The experimental degradation of a water soluble dye, potassium indigo tetrasulfonate salt, has been studied using stand-alone ozonation and photocatalytic oxidation process. Progress of the dye oxidation was followed by UV-VIS spectrophotometric measurements at controlled operating conditions. The organic content of reaction samples was measured to verify the process efficiency in dye mineraliz...

Membrane technique is a promising way for the removal of dyes from wastewater. A unique approach combining both the adsorptive and the catalytic membrane processes was proposed on the basis of a new functionalized membrane. The membrane integrating both the adsorptive and catalytic activities was developed by introducing polyoxometalates (POMs) as an ideal candidate for the membrane functionali...

The degradation of 2,6-dimethoxyphenol (DMP) and decolorization of Remazol brilliant blue R dye (RBB), added to culture media of Pleurotus ostreatus developed in submerged fermentation, and the laccase, manganese peroxidase and veratryl alcohol oxidase activities produced in these systems were evaluated. Both compounds were removed from the culture medium mainly by enzymatic action. These compo...

Dual purification of both oily wastewater and dye-polluted water for enhancing the use of freshwater is an urgent task. We report herein, the facile synthesis of inorganic semiconductor nanomaterials anchored mesh for in situ dual-functional water purification. This resultant mesh combines the excellent capacity of oil removal and the advantage of photocatalytic performance for dye degradation ...

The present investigation depicts the development of a simple and low cost method for the removal of color from textile dyeing and printing wastewater using ZnO as photocatalyst supported with porous activated carbon (AC). Photocatalytic degradation studies were carried out for water soluble toxic alizarin cyanin green (ACG) dye in aqueous suspension along with activated carbon (AC) as co-adsor...

The azo dye acid red 151 (AR151) was aerobically biodegraded in a sequencing batch biofilter packed with a porous volcanic rock. AR151 was used as the sole source of carbon and energy for acclimated microorganisms. Acclimation was followed using the degradation time and the oxygen uptake rate. A maximal oxygen uptake rate of 0.5 mg O(2)/(lmin) was obtained. Mineralization studies showed that 73...
