BACKGROUND Reactive Red 31, applied extensively in the commercial textile industry, is a hazardous and persistent azo dye compound often present in dye manufacturing and textile industrial effluents. Aspergillus bombycis strain was isolated from dye contaminated zones of Gujarat Industrial Development Corporation, Vatva, Ahmedabad, India. The decolorization potential was monitored by the decrea...
We report an environmentally friendly synthetic strategy to fabricate reduced graphene oxide (rGO)-based ternary nanocomposites, in which glutathione (GSH) acts both as a reducing agent for graphene oxide and sulfur donor for CdS synthesis under modified hydrothermal (MHT) conditions. The report becomes interesting as pH variation evolves two distinctly different semiconducting nanocrystals of ...
Decolorization of synthetic azo dye solution of Congo red dye, as an anionic dye was studied in a batch reactor using Advanced Oxidation Process (AOP). Congo red has been selected amongst azo dyes due to its high solubility in aquatic environment. AOP is effectively removing color in azo dye wastewater due to its strong oxidizing property by breaking down the functional group that impacting col...
background: the presence of even a very small quantity of dye in water bodies is undesirable and affects the water bodies. dye removal from industrial waste water is significant; hence in this study, a material that is an economical waste product was employed to test its acid dye removing capacity from aqueous solution. methods: in this study, batch mode experiments were performed in the sorpti...
This study measures the influence of pH and polyaluminium chloride (PAC) dosage on the effectiveness of reactive dyes removal. Experiments were carried out for turquoise DG, red DB-8, orange OGR and black DN. The pH was changed from 3.5 to 7.0 and the dosages of PAC from 0.3 to 4.0 mg Al/mg dye. The degree of dyes removal depended on pH and dosage of coagulant. In the pH range from 4.0 to 5.5 t...
A simple and rapid analytical method for the determination of trace levels of five sulphonated and azo sulphonated reactive dyes: Cibacron Reactive Blue 2 (C-Blue, trisulphonated dye), Cibacron Reactive Red 4 (C-Red, tetrasulphonated azo dye), Cibacron Reactive Yellow 2 (C-Yellow, trisulphonated azo dye), Levafix Brilliant Red E-4BA (L-Red, trisulphonated dye), and Levafix Brilliant Blue E-4BA ...
The textile industry is a water intensive industry that produces a large amount of highly colored wastewater that must be properly treated before disposal or reuse. In the present study, to verify the possibility of reusing textile wastewater with nanofilteration (NF), an attempt was made to treatment of synthetic reactive dye aqueous solution by commercial nanofiltration membrane. Experiments ...
In the present study, various size of Zinc Oxide Nanoparticles (ZnO NPs) was synthesized via Sol-gel method. The photocatalytic activity of the synthesized ZnO NPs was investigated for the Decolourization of three different colored dyes viz. Congo Red, Acid Blue 9 and Coomassie Brilliant Blue R-250 under UV lamp. Zinc Chloride (Zncl2) and Sodium Hydroxide (NaOH) were ...
