Effects of azo dye on simultaneous biological removal of azo dye and nutrients in wastewater [PDF]

Royal Society Open Science, 2018
The potential disrupting effects of Azo dye on wastewater nutrients removal deserved more analysis. In this study, 15 days exposure experiments were conducted with alizarin yellow R (AYR) as a model dye to determine whether the dye caused adverse effects on biological removal of both the dye and nutrients in acclimated anaerobic–aerobic ...

Application of systematic evidence mapping to identify available data on the potential human health hazards of selected market-relevant azo dyes

Environment International, 2023
Background: Azo dyes are used in textiles and leather clothing. Human exposure can occur from wearing textiles containing azo dyes. Since the body’s enzymes and microbiome can cleave azo dyes, potentially resulting in mutagenic or carcinogenic ...

Effect of Reactive Black 5 azo dye on soil processes related to C and N cycling [PDF]

PeerJ, 2018
Azo dyes are one of the largest classes of synthetic dyes being used in textile industries. It has been reported that 15–50% of these dyes find their way into wastewater that is often used for irrigation purpose in developing countries. The effect of azo

Supramolecular properties of amphiphilic adamantylated azo dyes [PDF]

, 2021
Despite environmental and health risks, azo dyes are still very popular colourising agents; therefore, methods for removing the dyes and/or related pollutants from wastewater have been developed. We have incorporated a lipophilic adamantane cage into two

Synthesis, characterization, and application of novel aryldiazenyl disperse dyes on polyester fabrics

Scientific Reports, 2023
Azo dyes are widely used for dyeing polyester fabrics but require optimization of properties like color strength and fastness. Fourteen novel disperse azo dyes were synthesized from 2,3-naphthalenediol and aniline derivatives to examine their potential ...

Potential and prospects of reductases in azo dye degradation: a review

The Microbe
Synthetic dyes, particularly azo dyes, pose environmental and health risks because of their toxicity and persistence. To reduce these negative effects, it is necessary to degrade and detoxify these dyes into simple, non-toxic substances.

Azo Dyes and Heinz Bodies [PDF]

Occupational and Environmental Medicine, 1957
No general hypothesis has been advanced to explain the underlying cause of the appearance of Heinz bodies in erythrocytes. The initial observation of Riess (1882) on a case of potassium chlorate poisoning was followed by that of Heinz (1890) who administered phenylhydrazine to animals.
