Studies on decolorization of reactive blue 19 textile dye by Coprinus plicatilis
BACKGROUND Studies were carried on the decolorization of the textile dye reactive blue 19 (RB 19) by a novel isolate of Coprinus plicatilis (C. plicatilis) fungi. We describe an in vitro optimization process for decolorization and its behavior under different conditions of carbon and nitrogen sources, pH, temperature and substrate concentration. RESULTS The optimal conditions for decolorizati...
متن کاملEquilibrium and Kinetics Study of Reactive Blue 19 Dye from Aqueous Solution by a Rapid Adsorption Approach to Degradation
The present investigation assesses the application of ceric sulfate for the removal of the colorant reactive blue19 (R.B19) from synthetic wastewater. The adsorption characteristics and dye removal efficiency of adsorbent have been determined by investigating factors such as effect of pH (pHOptimum
متن کاملElectrochemical Degradation of Reactive Blue 19 Dye in Textile Wastewater
Textile wastewater is notoriously known to contain strong colour, a highly fluctuating pH and significant COD (Chemical Oxygen Demand) values. Because of these characteristics, treatment of these effluents has been rather difficult. Traditional methods for dealing with textile wastewater consist of various combinations of biological, physical and chemical methods. Because of the large variabili...
متن کاملDecolorization of simulated spent reactive dye bath using solar / TiO
Different parameters were investigated to evaluate their effect on the process removal efficiency of reactive dye from simulated spent reactive dye bath, by solar / TiO2 / H2O2, including H2O2 concentration, TiO2 loading and pH. As a result 99% of reactive dye can be removed at a TiO2 loading of 400mg/l, H2O2 concentration of 150 mg/l and of pH: 5.2. The effect of photo-catalytic deactivation o...
متن کاملOptimization and Mathematical Modelling of Sodium Hypochlorite Mediated Decolorization of DIAZO DYE (Direct Blue 14)
Synthetic organic textile dyes are recalcitrant compounds released directly by the textile processing units into water bodies are important class of water pollutants. Decolourization of textile diazo dye Trypan Blue (Direct Blue 14) was investigated using a strong oxidative agent sodium hypochlorite using chemometric tools. Statistical tools such as Box-Behnken Design was applied for the study ...
