Azo Dye Toxicity: a measure of toxic effect metabolized azo dyes have on the body
Azo dyes represent the world’s largest and most diverse group of synthetic dyes with uses spanning almost every industry (Pandey et al. 2007). Their significance to public health is great as these globally produced dyes have been proven to be carcinogenic upon biodegrading into their aromatic amines (Harmse 2013). But aside from their carcinogenic properties, azo dyes have another dangerous eff...
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 کاملKinetics of anaerobic biodecolourisation of azo dyes.
Kinetics of anaerobic biodecolourisation (methanogenic environment) of four azo dyes (Acid Orange 6, Acid Orange 7, Methyl Orange and Methyl Red) was investigated with regard to their electrochemical properties as well as under variation of dye and sludge concentrations, pH and temperature. Cyclic voltammetry revealed a correlation between the potential of irreversible reduction peak of the dye...
متن کاملStructure and carcinogenic activity of azo dyes.
In recent years many investigations have been carried out on the carcinogenic activity of several groups of derivatives of 4-aminoazobenzene, their spectra, the relative basicities of their nitrogen atoms, and their metabolism (1, 2, 9, 14). The principal results on the correlation of structure and activity are as follows: Methylation.--3'-Methyl-4-dimethylaminoazobenzene is a tvery potent carc...
