“…There are around 10,000 different industrial dyes and pigments, totaling an annual world consumption of 700,000 tons (Pearce et al, 2003), 26,500 tons of which are consumed in Brazil (Guaratini and Zanoni, 2000). Reactive Blue 5G is one of the main dyes used in dyeing facilities since it is used in the production of blue denim.…”

-In this study the influence of the volumetric flow rate and feed concentration was investigated for the adsorption of the reactive dye Blue 5G. Experiments were carried out in a bed packed with retorted shale, at 30 o C. The ranges investigated were flow rate 2 -10 mL/min and the feed concentration 13-105 mg/L. Mathematical models were used to represent the dynamic sorption. The double resistance model considers the effects of the axial dispersion and the mass transfer resistance of the external film and inside the particles. As a result, the mass transfer coefficient of the external film and the internal mass transfer coefficient were estimated. The Thomas model was used to simulate the experimental data. In this model the fitted parameter was the adsorption kinetic constant. The first model provided an acceptable representation of the dynamic uptake of the reactive dye Blue 5G.

“…The percentage removal of colour by S.aureus was 90.02% and that of E.coli was 88.7% at 37 0 C. Further increase in temperature resulted in the marginal reduction of decolourisation by S.aureus and E.coli. This is due to the loss of cell viability or to the denaturation of the azoreductase enzyme [8].…”

“…Several physico-chemical processes such as adsorption, chemical oxidation, filtration and incineration are used to treat wastewater containing dyes and dye products. These methods are rather expensive and produce hazardous byproducts [7] Biological decolourisation by fungi, algae, actinomycets and higher plants has been tried and seems to be an attractive method, because of their metabolic pathways and versatility of the microorganism [8]. The possibility of using bacteria to decolourise wastewater containing dyes is more advantageous, due to the presence of azoreductase enzyme which has the ability to degrade azo compounds.…”

Biodegradation of acid blue 113 has been studied using two strains-Staphylococcus aureus and Escherichia coli. The effect of pH, time, initial dye concentration, the inoculum size, the co-substrate, static and shaking on decolourisation was studied. The optimum condition for decolourisation was found to be at pH 7 for an initial dye concentration of 200 mg/L at 37 ̊C under static condition. The removal of dye by S.aureus and E.coli at optimum condition was 90% and 88% within 30 h and 42 h respectively. Addition of fructose and starch as carbon source increased the removal of colour by S.aureus and E.coli respectively. Similarly addition of ammonium formate and glycine as nitrogen source under static condition increased the colour removal by S.aureus and E. coli. The enzyme activity of azoreductase for S. aureus and E. coli was found to be 7.33 U/ml and 7.24 U/ml respectively. The COD reduction, FTIR and TLC analysis of the sample before and after decolourisation confirmed the biodegradation of dye and the formation of new metabolite. Phytotoxicity studies indicated that the microbial treated effluent is safe for disposal into the environment. .

ABSTRACT:The kinetics of oxidative decolorization of acid orange 10 (AO10) by chloramine-B and bromamine-B in HClO 4 medium has been investigated spectrophotometrically (λ max = 475 nm) at 298 K. Kinetic runs were performed under pseudo first-order conditions of [oxidant] [HClO 4 ]. Stoichiometry of the reaction was found to be 1:1 and the oxidation products were identified. The reaction was studied at different temperatures and various activation parameters have been computed. Effects of p-toluenesulfonamide, halide ions, ionic strength and dielectric constant of the medium have been investigated. Reaction mixture fails to induce polymerization of acrylonitrile. The rate of oxidation of AO10 is about two-fold faster with BAB as compared to CAB. This may be attributed to the difference in electrophilicities of Cl + and Br + ions and also the van der Waal's radii of chlorine and bromine. Plausible mechanism and related rate law have been deliberated for the observed kinetics.
