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 work looks for a better understanding of the biodegradation of xenobiotic azo dyes mediated by yeasts. During a screening program of phenolic acid assimilating capacities it was found that a non-conventional ascomycetous yeast isolate, identified as Candida oleophila, efficiently decolorizes agar plates supplemented with the commercial textile diazo dye Reactive Black 5. Aerobic batch cult...

The nanoparticles of templated crosslinked chitosan, was prepared through using ECH as a crosslinker. The nanoparticles exhibited significantly higher adsorption capacities from the congo red dye than other adsorbent formed without a crosslinker. The adsorption of the dyes on the nanoparticles was affected by the initial pH, dye concentration, and temperature. The results were in accordance wit...

Abstract Dye is a major source of water pollution. This mini-review highlights the origin dye, its removal strategies, and recent literature methylene blue Congo red adsorption by activated carbons. Adsorption unique process that relies upon physicochemical properties carbon inherent characteristics dye. Also, factors affecting adsorption, such as contact time, temperature, concentration, were ...

biosorption of acidic dyes using the live fern azolla filliculoides was studied in a discontinuous system. dye parameters, dye initial concentration and contact time were studied in temperature range of 25-30 ?c and ph=7. it was shown that increasing the 23initial concentration of dye and its contact time resulted in decreasing the dye taking quantity by the absorbent. also, type of dye has an ...

an agricultural waste and eco-friendly biosorbent i.e. rice husk has been used as a cheap adsorbentfor the removal of methylene blue dye from aqueous solutions. the physical properties of the developedadsorbent were characterized using ftir. the study was realized using batch experiments. the effectsof contact time, ph, initial dye concentration, biosorbent dose and temperature were investigate...

−N-succinyl-chitosan-g-polyacrylamide/attapulgite (NSC-g-PAM/APT) composite was applied as adsorbent for the removal of methylene blue (MB) from aqueous solution. The initial pH value of the dye solutions, the contact temperature, the contact time and the concentration of the dye solutions on adsorption capacity of the composite for MB dye were investigated. The adsorption kinetics and isotherm...

Adsorbent prepared from waste plants for the treatment of dyeing effluents have high significance in environmental sustainability. In this research, adsorption of Acid Blue 92AB 92 dye from aqueous solutions on raw and modified diatomite nickel oxide nanoparticles was studied. The effect of different operation parameters such as pH, contact time, initial dye concentration, calcinations and sorb...
