Biodegradation is a cost-effective method to remove the residues of azo dyes prior to their discharge in wastewater streams from dye product industries. The efficacy of this treatment method is highly dependent on establishing an effective degrader community and maintaining environmental conditions that support the growth and activity of the degrader ...

Heterocyclic azo dyes. IV. Azo Dyes Containing the Quinoline Nucleus
Journal für Praktische Chemie, 1973AbstractThe synthesis, some dyeing and fastness properties of several new monoazo dyes derived from 6‐amino‐ and 6‐hydroxy‐quinolines when applied as dispersed dyes on nylon 6 are described. Preliminary correlations between light fastness and chemical structure are attempted.

The significance of azo-reduction in the mutagenesis and carcinogenesis of azo dyes
Mutation Research/Reviews in Genetic Toxicology, 1983Azo dyes are widely used in textile, printing, cosmetic, drug and food-processing industries. They are also used extensively in laboratories as either biological stains or pH indicators. The extent of such use is related to the degree of industrialization.

Acta Polymerica, 1987
AbstractA series of new polymerizable azo dyes containing the methacryloyloxy group were prepared. Their melting points, yield, colour, solubility and absorption in the UV‐visible range were characterized, and the relationship between their properties and structure was evaluated. The characteristics of radical homopolymerization of one of the azo dyes,

Spectroscopic ellipsometry investigation of azo dye and azo dye doped polymer
The European Physical Journal Applied Physics, 2006The 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 (

Heterocyclic azo dyes. I. Azo Dyes Containing the Benzotriazole Nucleus
Journal für Praktische Chemie, 1967AbstractThe synthesis, some dyeing, and fastness properties of several new dispersed, acid, and direct dyes derived from the aminobenzotriazoles (I–IV) and 5‐hydroxybenzotriazole (V) are described. The suitability of the amino derivatives (I–IV) as bases for azoic dyeing has also been studied.
