Among the 30 strains of moderately halophilic bacteria isolated from the salty effluents of textile industries around Qom city in central Iran, a Gram-negative rod shape bacterium designated as strain IP8 showed a remarkable ability in decolorizing of azo dyes over wide ranges of pH (7-11) and temperature (25-45 ºC), in presence of NaCl and Na2SO...
In this study, decolorization of the diazo dye, Reactive Black 5 (RB5) in a Coprinus cinereus peroxidase-catalyzed reaction has been investigated. A bisubstate kinetic model for the reaction rate based on the Ping-Pong mechanism was assumed for the enzymatic decolorization. Experiment...
The present study deals with the decolorization of CI Acid Red SR (ARAN as a model contaminant from textileindustry using sawdust as an adsorbent. The effects of initial AR88 concentration, adsorbent dosage, pH. c not acttime and ',riming rah: wcrg studied in a batch mode. The variation of pH from 3 to 10 showed no considerablechange in decolorization rate. The desired conditions for decoloriza...
Decolorization of Reactive Black 5 (RB5) was investigated by heterogeneous photocatalysis using N-doped TiO2. TiO2 photocatalysts were synthesized means a sol-gel process. X-ray diffraction performed the characterization samples, scanning electron microscopy and photoelectron spectroscopy measurements. Photocatalytic activity samples assessed following decolorization degradation efficiency RB5....
This research investigated the production of porous zinc oxide (ZnO) ceramics obtained by replica method for water depollution photocatalytic processes. Five photo-decolorization cycles were performed to analyze reuse potential ceramics. Statistical analyses using R programming conducted investigate possible significant differences between them. The porosities 46.74 and 62.50% (depending on com...

problematic dyes extensively used in different industries such as textile, paper, food, plasticsand cosmetics have undesirable environmental effects. white rot fungi demonstrating effective extracellularenzyme system, which is capable of degrading dyes and various xenobiotics. the aim of this study was tooptimize decolorization of reactive blue 19 (rb19) dye using phanerochaetechrysosporium. a ...
Degradation of dyes especially, azo dyes are difficult due to their complex structure and synthetic nature. The main objective of this study was to evaluate the Fenton-biological (aerobic) treatment train for decolorization and mineralization of azo dyes viz. Reactive Black 5 (RB5), Reactive Blue 13 (RB13) and Acid Orange 7 (AO7). The objective of Fenton treatment was only to decolorize the dye...
