In the present study, the photocatalytic decolorization of biebrich scarlet dye (BS) has been investigated in a batch reactor under UV light in slurry mode using different nanophotocatalysts (TiO2, ZnO, CdS and ZnS). ZnO was found to be a better photocatalyst among others for the decolorization of BS. The optimum values of different parameters viz....

In the present study a flower like ZnO nanostructure has been synthesized by using simple hydrothermal route without any catalysts, templates or substrates. The phase structure and morphology of the synthesized ZnO has been characterized by XRD, SEM and TEM. The room temperature photoluminescence (PL), diffuse reflectance spectra (DRS), FT-IR spect...

In the present study the photocatalytic decolorization of pararosaniline chloride dye (unhydrolysed and hydrolysed forms) and its simulated dyebath effluent has been investigated by employing heterogeneous photocatalysis process. The photocatalytic activity of different semiconductors viz. TiO2, ZnO, CdS and ZnS has been compared in order to select...

In this study, sol–gel method was employed for the synthesis of nanosized ZnO. The phase structure and morphology of the synthesized ZnO was characterized by XRD, SEM and TEM. The FT-IR spectra, room temperature photoluminescence (PL) spectra, diffuse reflectance spectra (DRS), and BET surface area were also examined. Then the efficacy of the synth...

Abstract Environmental problems associated with hazardous wastes and toxic water pollutants have attracted much attention. Among them, organic dyes are one of the major groups of pollutants in wastewaters produced from textile and other industrial processes. Among various physical, chemical and biological techniques for treatment of wastewaters, he...

The present work is aimed at investigating the capability of chemically modified rice husks (MRH) for the reduction of aniline ions from industrial wastewater. The experiments have been conducted to examine the influence of four operating parameters in the batch adsorption technique. The effect of initial concentrations of aniline (10-100) mg.L-1,...

Arsenic (V) is represented as a very toxic compound, hence the importance of this research is concerned to reduce AS (V) from contaminated water before emitting it into river water by using modified spent tea leaves MSTL. The effect of arsenic initial concentration (10-100) mg.L-1, the mass of MSTL (0.1-0.6) g.L-1, pH (2-10), and mixing time (10-11...

This study examined the use of Onion Skins, an inexpensive adsorbent material, for removing the Methyl Violet dye which represents the main objective by using batch adsorption process to investigate and understand the adsorption behaviour, the kinetics and the equilibrium isotherm using a low-cost adsorbent. The study included the influence of cont...

In this work, the photocatalytic is related to simulated wastewater as well as recycling for industrial uses. Photocatalytic degradation of simulated wastewater content (Eosin Yellowish, Eriochrom Black T, Methyl Violet, EDTA, FeSO4.7H2O, NaCl, and NaOH) was utilized as a treatment approach in batch reactors within solar light in a heterogeneous sl...

The purpose of this work is to examine the ability of activated carbon derived from agricultural wastes for removing methylene blue dye from industrial wastewater. The influence of operating factors for the adsorption process was included initial methylene blue dye, activated carbon dosage, the acidity of wastewater, and contact time. The experimen...

Eosin yellowish was intended to be degraded by the use of photo catalysis process which is proposed to be mediated by ZnO and irradiated under visible light. Effects of variant swayful factors were studied for instance dosage of catalyst, concentration of dye and the incipient pH. A huge number of intermediates which yielded from photo degradation...

The degradation of eosin yellow dye using ZnO as a photo catalysts in a slurry reactor exposed to solar light was studied by this paper . The optimum values of different parameters versus catalyst concentration, catalyst type and initial concentration of the substrate affecting the degradation rate of eosin yellow dye were obtained by varying catal...

The industry of textile exhausts large volume of water by different wet processes. The enormous amounts produces of textile waste water heavily charged with un-consumed dyes and other compounds. These dyes involve some kinds of structural of dyes such acidic, basic, reactive and dyes with metal complex structure. Dyes (and their derivatives) repres...

This research paper study, the treatment of m ethylene blue dye was investigated in a photo catalytic system under solar irradiation in heterogeneous solution with multi concentrations like (0.3, 0.8, 1.3, and 2) g/l of commercial TiO2 as a photo catalyst. The optimum value of photo catalyst concentration (0.8 mg/l) the nano particles TiO2 was prep...

In the present paper, the degradation of Methyl Orange dye using two commercial photocatalysts (ZnO and TiO2). These two catalysts have been tested and compared in suspension in a slurry reactor under solar light. The best values of various transactions such as catalyst concentration, catalyst type and the concentration at the beginning of experime...

The potential use of dried anaerobic granular sludge (DAGS) as a substitute for granular activated carbon (GAC) for removing phenol and lead from aqueous solution was examined in a batch system. To make the comparison between adsorption/biosorption process fair, the working sorption pH, temperature, mixing speed and contact time were fixed at 4, 30...
