Application of immobilized horseradish peroxidase for removal and detoxification of azo dye from aqueous solution
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...
متن کاملBiodegradation of azo dye compounds
Azo dyes are one of the oldest industrially synthesized organic compounds characterized by presence of Azo bond (-N=N-) and are widely utilized as coloring agents in textile, leather, cosmetic, paint, plastic, paper, and food industries During textile processing, inefficiencies in dyeing result in large amounts of the dyestuff (varying from 2% loss when using basic dyes to a 50% loss when certa...
متن کاملProbing horseradish peroxidase catalyzed degradation of azo dye from tannery wastewater
Biocatalysis based effluent treatment has outclassed the presently favored physico-chemical treatments due to nil sludge production and monetary savings. Azo dyes are commonly employed in the leather industry and pose a great threat to the environment. Here, we show the degradation of C. I. Acid blue 113 using horseradish peroxidase (HRP) assisted with H2O2 as a co-substrate. It was observed th...
متن کاملPhotoinduced birefringence and diffraction efficiency in azo dye doped or grafted polymers: theory versus experiment of the temperature influence
We have investigated the influence of the temperature on the photoinduced birefringence as well as on the diffraction efficiency of azo dye doped or grafted polymers. The samples are composed of three polymer matrices containing 2, 5-dimethyl-4-( p-nitrophenylazo anisole). We propose two theoretical models to explain the experimental increase of both phenomena when the temperature is decreased....
متن کاملAnchoring properties of photoaligned azo-dye materials.
The photoinduced alignment of a liquid crystal (LC) on films of azo dyes was studied for the liquid crystal display applications. In order to improve the alignment stability of the photoaligned dye (SD-1), the azo-dye derivative with polymerizable terminal groups was synthesized (SDA-1). The films of SDA-1 exhibit good photoalignment properties and ultraviolet stability after thermal polymeriza...
