The photocatalytic degradation of dye Rhodamine B (RhB) in the presence of TiO2 nanostripe or P25 under visible light irradiation was investigated. The degradation intermediates were identified using Infrared spectra (IR spectra), 1H nuclear magnetic resonance (1HNMR) spectra, and gas chromatography-mass spectroscopy (GC-MS). The IR and the 1HNMR results showed that the large conjugated chromop...

This study is focused on development of a method of TiO2 immobilization, convenient for the wastewater remediation (especially for the degradation of textile dyes) and cheap for an industrial operation. An influence of selected operational parameters on process performance was verified. Methylene Blue was chosen as the model dye, however, a possibility of decolorization of other dyes was also t...

Dyes are one of the most important existing pollutants in textile industrial wastewater. These compounds are often toxic, carcinogenic, and mutagenic to living organisms, chemically and photochemically stable, and non-biodegradable. Acid red 18 is one of the azo dyes that are currently used in the textile industries. Photocatalytic degradation offers a great potential as an advanced oxidation p...

Methyl red, a synthetic azo dye, was reported for not only being mutagenic but also its persistence has severe consequences on human health, such as cancer, alongside detrimental environmental effects. In the present study, Pseudomonas putida OsEnB_HZB_G20 strain isolated from soil sample to study catalytic activity degradation of methyl red dye. Another strain, aeruginosa PA 1_NCHU used an ele...

Textile dye industry waste is one of the most serious problems in the environment. The dye wastes are severely deleterious to surface water bodies. The present study was an attempt for the assessment of different physicochemical parameters such as pH, temperature, Electrical Conductivity (EC), Total Solids (TS), Total Dissolved Solids (TDS), Total Suspended Solids (TSS), Dissolved Oxygen (DO), ...

In this study, we used advanced oxidation process (AOP)for the removal of a cationic and anionic blue dyes, namely Basic Blue 3 (BB3) and Acid blue 62(AB62), from aqueous solutions. Fenton reactions are mixture of H2 O2 and Fe2+. However this paper investigates the application of twelve different catalysts such as: FeCl2 , FeSO4, (NH4 )Fe(SO4 )2 , FeCl3 , Nano iron (Fe0 ), Fe(NO3 )3 , K2FeO4 , ...

Recently, the research on remediation of aqueous organic pollutants over visible-light-active photocatalysts has got much attention. Therefore, this study reports fabrication Co3O4-Bi2O3 heterojunction photocatalyst for photodegradation rhodamine B dye. The was synthesized by coprecipitation method and characterized XRD, EDS, SEM, TEM, TGA, FTIR. as-prepared utilized as a abatement It observed ...

The present study describes the green synthesis of TiO2 nanoparticles using Sesbania Grandiflora and Solanum nigrum leaf extracts. characterisation synthesised is carried out XRD FTIR. photo catalytic degradation Rhodamine-B dye carry under sunlight irradiation by UV- Vis spectrophotometer. Among synthesized catalysts, SG/TiO2 was found to be best for photocatalytic dye. degraded water also tes...

The high demand for dyes in the paper, cosmetic, clothing, leather, and food industries drives up use of as a result industrialization. As result, wastewater production from dye manufacturing activities will rise. presence their structural compounds industrial sources place humans, animals plants lives at risk. Synthetic are more challenging to decolorize because they resistant chemical physica...
