Dyes are threat to aquatic as well as human life. These are often introduced in the water bodies from textile or paper industries with improper treatment. Chemical treatments for dye decolorization are quite costly; another disadvantage is decolorization of these dyes is not complete. The bacterial flora in the effluent of textile industries is continuously exposed to dyes. Few of this might be...

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...

suffering from a deficiency of vitamin C. Portnoy and Wilkinson (1938) confirmed the results obtained by Rotter. They also stated that they found a good correlation between the level of blood ascorbic acid and the decolorization time of the intradermal test in 103 patients. Later, Wright and MacLenathen (1939) who also investigated dietary history and determined blood ascorbic acid levels, gave...

Graphite/NiO/Ni electrode had been fabricated for the electro-oxidation of remazol black 5 dye. The was synthesized by electrodeposition method. Electro-oxidation 100 ppm dye carried out at various concentrations NaCl, 0.025; 0.05; 0.1; 0.25; and 0.5 M, variations in time were 15, 30, 45, 60 minutes, pH 4, 6, 8. Cyclic voltammetry test revealed that graphite/NiO/Ni higher electrocatalytic capab...

A photocatalytic rotating disc reactor (PRD-reactor) with TiO₂ nanowire arrays deposited on a thin Ti plate is fabricated and tested for industrial wastewater treatment. Results indicate that the PRD-reactor shows excellent decolorization capability when tested with methyl orange (>97.5%). Advanced oxidation processes (AOP), including photocatalytic oxidation and photolytic reaction, occurred d...

In this paper, the photochemical degradation of azure-b by Cu2+/S2O82− process has beenpresented. Cu2+ as photocatalyst and S2O82− ion as photooxidant used in this process. Atextremely low concentrations, cupric ion showed true catalytic activity in the overall process.The influence of various parameters on the performance of the treatment process has beenconsidered, such as pH, concentration o...

This study reports the analogies and differences found when comparing TiO(2) photocatalytic treatment for chemical oxidation and microorganisms inactivation, using methylene blue and Escherichia coli as references, respectively. In both processes the activation is based on the same physicochemical phenomena and consequently a good correlation between them is observed when analyzing the effect o...

This study evaluated the effect of addition green iron microparticles (Fe-MPs) as a three-dimensional electrode on efficiency electrochemical oxidation process. Polyphenols present in tea extract act reducing and capping agent during synthesis Fe-MPs. Scanning electron microscopy energy-dispersive X-ray spectroscopy analysis indicates that average size particles is 100 µm, with about ~47 wt % F...

This study focused on the effects of electro-oxidation combined with electro-Fenton process using boron-doped diamond (BDD) electrodes degradation biorefractory food colorant caramel. Aqueous solutions containing Caramel Class IV, III and Acid Orange 7 were comparatively treated by electrochemical advanced oxidation processes, including (EO), (EF) (EO + EF). The experiments performed in a stirr...
