in this research we have developed a treatment method for textile wastewater by tio2/sio2-based magnetic nanocomposite. textile wastewater includes a large variety of dyes and chemicals and needs treatments. this manuscript presents a facile method for removing dyes from the textile wastewater by using tio2/sio2-based nanocomposite (fe3o4@sio2/tio2) under uv irradiation. this magnetic nanocompo...

Background: Textile industry has been condemned as one of the world’s worst offenders in terms of pollution because 10-15% of all the dyes used in the industry are lost within wastewater during processing. The presence of even very low concentrations of dyes in effluent is highly visible and degradation products of these textile dyes are often carcinogenic. Owing to the complex nature of synthe...

The present study was taken up as an exploratory study to test if some natural dyes have inherent antimicrobial activity with a view to develop protective clothing from these. Four natural dyes Acacia catechu, Kerria lacca, Quercus infectoria, Rubia cordifolia and Rumex maritimus were tested against common pathogens Escherichia coli, Bacillus subtilis, Klebsiella pneumoniae, Proteus vulgaris an...

introduction: textile industries produce large volume of colored dye effluents which are toxic and removal of dyes from wastewater is a significant environmental issue. advanced oxidation process (aops) is alternative method for the complete degradation many organic pollutants. zno and tio2 are important photocatalysts with high catalytic activity that have attracted much research attention. ma...

A first-order derivative spectrophotometric method for the simultaneous determination of three textile dyes, Procion Yellow HE4R, Procion Red HE7B and Remazol Black 5 (RB5), has been developed. The effects of pH, heating and ionic strength of the solution on the absorption spectra of the dyes were investigated. The wavelengths selected for the measures of the derivative signals of HE4R (395 nm)...

Contact allergy to disperse dyes in textiles is documented in prevalence studies from southern Europe. To evaluate the prevalence of allergic patch test reactions to different textile dyes in southern Sweden, and to look at the sites of dermatitis in individuals hypersensitive to textile dyes, we retrospectively investigated 3325 consecutively patch-tested patients. They had all been patch test...

The large number of publications in the field of extraction, purification, modification, and process optimization of natural dyes and their application on textiles demonstrates the revival of natural dyes on textile coloration. The use of natural dyes is growing in popularity because of the quality of the natural dyestuff obtained, the environmental compatibility of the dyes and the substantial...

backgroud and purpose: dye is one of the problems of industrial effluent such as textile industries. the dyes can be removed by various methods. therefore, the aim of this study was the evaluation of adsorption rate of reactive red 198 from aqueous solution by activated red mud. materials and methods: this research was a lab study. activated red mud was used as an adsorbent to remove reactive r...

this paper reports application of cetyltrimethylammonium bromide (ctab) coated magnetite nanoparticles (fe3o4 nps) as a novel adsorbent for removal of two types of disperse dyes, including disperse red 167, and disperse blue 183, from wastewater of textile companies. the effect of parameters including type of surfactant, ph of solution, surfactant concentration, and amount of salt, was investig...

Treatment of effluents containing phenols such as textile dyes with fungal laccases is usually limited to the acid to neutral pH range and moderate temperatures. Here we demonstrate for the first time that spore-bound laccases which are stable at high temperatures and pH values can be used for phenolic dye decolorisation. Laccase containing spores from Bacillus SF were immobilized on alumina pe...
