The development and application of an immobilized horseradish peroxidase (HRP) on calcium alginate gel beads are reported for the successful and effective decolorization textile industrial effluent. The optimal condition for the immobilization of HRP on calcium alginate gel beads which leads to a specific activity of 15 U/g calcium alginate was identified. Upon immobilization, considering enzym...

Textile waste water treatment for industrial reuse remains as a complicated problem due to several reasons. Among them are: 1) Higher levels of Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD) and Total Dissolved Solids (TDS) content of the waste water; 2) Non-biodegradable nature of organic dye stuffs present in the effluent. Thus, any adopted treatment system, especially with resp...

Abstract The aim of this work was a complete thermodynamic study on the partitioning Remazol Yellow l, Brilliant Blue, and Red dyes in isopropyl alcohol + sodium phosphate water aqueous two‐phase systems at different temperatures. free energy change transfer, enthalpy entropy transfer were evaluated. effects structure dye, tie line length, temperature studied. results indicate that these have h...

Dye decolorizing bacteria was isolated and identified from textile effluent samples. The isolate was identified as Bacillus licheniformis by 16S rDNA sequencing. Azoreductase, an enzyme responsible for catalyzing the reductive cleavage of azo bonds was purified from B.licheniformis. The enzyme was purified by a combination of ammonium sulphate precipitation, ion exchange and affinity chromatogr...

Isolation of lignin degrading microorganisms from cow dung, soil compost, and paper pulp effluent was carried out in the present investigation. Totally 9 isolates of lignin degrading microbes were isolated using minimal salt media containing lignin (MSM-L) and lignolytic activities were preliminary screened by testing against methylene blue indicator dye containing LB medium. Eight microbes sho...

Peanut hull, an agricultural waste, proved to act as an efficient adsorbent for five anionic and cationic dyes. The process was found to be a pH dependent, suggesting the adsorption is controlled by interaction between the charged dye molecule and the surface charge on the adsorbent. The effect of variable parameters (contact time, pH, mass of adsorbent, dye concentration, agitation and activat...

Abstract The use of dimensionally stable anode (DSA) for degrading organic pollutants is concern recently. electrocatalytic technique can efficiently treat biodegradable matter like dye-containing effluent discharge. This study focuses on applying modified DSA meshed IrO 2 /Ti electrode the electrochemical degradation wastewater effluents Basic Red 46 (BR46) textile dye using different supporti...

This study presents a novel method for eco-friendly dyeing of cotton fabrics with direct dyes. Cotton fabric modified with chitosan-poly propylene imines dendrimer CS-PPI, and its dyeing and fastness properties were investigated using three direct dyes. The impacts of important factors, i.e., CS-PPI concentration, dye concentration, dyeing time, dyeing temperature, and salt concentration were i...

Abstract The treatment of azo dye effluent from the dyeing process, as well sustainable development environment, can all be achieved through use green mycoremediation. In this in vitro study, Trichothecium roseum was isolated by sedimentation technique environment an unplasticized polyvinyl chloride pipe manufacturing plant and used to decolourize optimise biosorption percentage Azo Lanasyn Nav...
