NPS SYNTHESIS, CHARACTERIZATION AND AZO-DYE DEGRADATION A facile cost effective wet chemical method of synthesis is proposed for Cu-NPs, CuO-NPs and Cu-doped ZnO-NPs. The nanomaterials are opto-physically characterized for nano standard quality. Cu-doped ZnO-NPs based catalytic system is found to possess most efficient photocatalytic activity in degradation of two organic azo-dyes namely methyl...

The recycling of mineral tailings is an important research topic. In this work, composite material was prepared using vanadium titanomagnetite (VTM) tailings, kaolin and sodium silicate, used as a photocatalyst for photocatalytic degradation organic dyes. results showed that the has good performance on rhodamine B in solution within few minutes. synthesized materials were characterized by XRF, ...

In this paper, CuO-ZnO nanocomposite was synthesized and its photocatalytic dye degradation ability from colored wastewater was studied. Basic Red 18 (BR18) and Basic Violet 16 (BV16) were used as model dyes. The characteristics of CuO-ZnO of were investigated using Fourier transform infrared (FT-IR) spectroscopy, scanning electron microscope (SEM) and X-ray diffraction (XRD). Photocatalytic dy...

UNLABELLED BACKGROUND The discharge of wastewater that contains high concentrations of reactive dyes is a well-known problem associated with dyestuff activities. In recent years, semiconductor photocatalysis has become more and more attractive and important since it has a great potential to contribute to such environmental problems. One of the most important aspects of environmental photocat...

Hydrogels have excellent properties that make them ideally suited as host matrices for the immobilization of photoreactive materials such TiO2 nanoparticles serve catalysts in photodegradation organic dyes, which is great importance practical water pollution treatment applications. However, application hydrogels this purpose remains poorly studied. The present study addresses issue by developin...

In this paper we used two free-metal organic dyes (dye 1 and dye 2) based on indigo and thioindigo with cyanoacrylic acid as the electron acceptor group. The proposed dyes were sensitized from naphalene as the starting material by standard reactions and characterized by different analytical techniques and UV-Visible spectroscopy after purification. Spectrophotometric measurements of the organic...

Removal of a commercial dye (Procion yellow H-EXL) in both synthetic and real wastewater from textile industry over TiO2 suspension has been investigated. The study included both adsorption process (over TiO2) and photocatalytic degradation process in the presence of UV illumination (UV/TiO2). The processes were carried out in aqueous solutions containing the dyes in the presence of titanium di...

Article history: Received 30 August 2017 Accepted 18 September 2017 Available online 02 October 2017 The textile industry is a field which has strong environmental impacts due its high consumption of water and emission of pollutants, specially the dyes. The dyes are organic or synthetic substances which alter the physicochemical characteristics of the water body in which they are released, incr...
