Background: Dyes have complicated structure, are usually toxic and resistant to biological treatment which entere into environment by industrial waste streams. The aim of this study was the removal of reactive red 198 dye (RR 198) by photolysis (UV) and photocatalytical (TiO2/UVC) processes. This study was conducted to investigate the effects of dye concentration, pH, TiO2 dose, and contact tim...

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 ...

In the present study, the biobleaching potential of white rot fungus Cordyceps militaris MTCC3936 was investigated. For preliminary screening, decolorization properties of C. militaris were comparatively studied using whole cells in agar-based and liquid culture systems. Preliminary investigation in liquid culture systems revealed 100% decolorization achieved within 3 days of incubation for rea...

Synthetic organic colourants, the majority of which are recalcitrant in nature, are used in many different manufacturing processes. The dyes are released into the environment in industrial effluents and are highly visible even at low concentrations (< 1 mg/l). Decolorisation of the dye CI Reactive Red 141 was investigated in a laboratory-scale anaerobic baffled reactor (ABR). The results of the...

&nbsp; &nbsp; Background &amp;amp; Aims of the Study: Textile wastewaters are very various in chemical qualities. In other words, these industries are one of the largest producing dyes compounds; therefore their treatment is so complex and difficult. The aim of this study was to evaluate the potential removal of Reactive Red 198 and Blue Reactive 19 from synthetic solution by Acaciatortilis shu...

The ability of two varieties (hard and soft) of almond peels, as inexpensive sorbents for the removal of bezanyl red (acid dye) from synthetic aqueous solutions has been studied. After their characterization by different techniques, (elemental analysis, biochemical analysis, IR spectroscopy, thermogravimetric analysis, scanning electron microscopy and mercury porosimetry), the dye sorption kine...

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...
