Bioreactors for Azo-Dye Conversion

, 2010
This chapter embodies two sections. In the first section a survey of the state of the art of azo-dye conversion by means of bacteria is presented, with a focus on reactor design and operational issues. The relevance of thorough characterization of reaction kinetics and yields is discussed.

Spectroscopic ellipsometry investigation of azo dye and azo dye doped polymer

The European Physical Journal Applied Physics, 2006
The optical constants of azo dye (Methyl Red (MR)) and azo dye doped polymer (ADP) (Polymethylmethacrylate (PMMA)) MR/PMMA have been investigated using Variable Angle Spectroscopic Ellipsometry (VASE). Pure MR was modeled using Lorentz formula with three oscillators. A Bruggmann effective medium approximation layer was employed with three constituents (

Biogenic sulfide for azo dye decolorization from textile dyeing wastewater

Chemosphere, 2021
Azo dye is the most versatile class of dyes used in the textile industry. Although the sulfidogenic process shows superiority in the removal of azo dye, the role of biogenic sulfide produced by sulfate-reducing bacteria (SRB) in the decolorization of azo

Treatment of azo dye-containing synthetic textile dye effluent using sulfidogenic anaerobic baffled reactor

Bioresource Technology, 2013
This study aims at investigating azo dye reduction performance of a sulfidogenic anaerobic baffled reactor (ABR) for around 400 days. ABR was operated at 30 degrees C in a temperature-controlled room and hydraulic retention time (HRT) was kept constant ...

Picosecond Switchable Azo Dyes

Chemistry – A European Journal, 2019
AbstractAzo dyes that combine electron‐withdrawing thiazole/benzothiazole heterocycles and electron‐donating amino groups within the very same covalent skeleton exhibit relaxation times for their thermal isomerization kinetics within milli‐ and microsecond timescales at room temperature.

Degradation of azo dyes by algae

Environmental Pollution, 1992
The degradation of azo dyes by algae was evaluated and it was found that certain algae can degrade a number of azo dyes to some extent. The reduction rate appears to be related to the molecular structure of the dyes and the species of algae used. The azo reductase of algae is responsible for degrading azo dyes into aromatic amine by breaking the azo ...
