Papita, Plant-mediated synthesis of silver-nanocomposite as novel effective
azo dye adsorbent, Appl.
Aerobic decolorization and degradation of
azo dyes by growing cells of a newly isolated yeast Candida tropicaiis TL-F1.
Similarly three types of structurally different four
azo dyes Reactive Black 5, Reactive Blue BRS, Direct Blue and Disperse Yellow were used for enrichment of the medium to isolate bacteria.
Several authors like Oforka and Oranusi (20) have reported decolorization of
azo dyes like Ponceau 4R dye and carmoisine by Escherichia coli, the strain used in their study was originally obtained from the Department of Microbiology at the University of Port Harcourt in Nigeria and was isolated from the natural human intestinal flora.
The stability of textile
azo dyes in soil and their impact in microbial phospholipid fatty acid profiles.
Modified graphene quantum dots have been used in this research as nanocatalyst to synthesize
azo dyes.
It has been found that purified forms of many
azo dyes are directly mutagenic and carcinogenic (Chen, 2002).
Removal of a hazardous
azo dye (Basic Red 46) from aqueous solution by princess tree leaf.
They are: Erythrosin included in the class of xanthene dyes; Blue indigotine included in the indigotin class of dyes, Patent Blue V, Fast Green and Brilliant Blue in class of triphenylmethane dyes, Bordeaux Red, Ponceau 4R, Red 40, Azorubine, Tartrazine Yellow and Sunset Yellow, included in the class of
azo dyes (POLONIO; PERES, 2009).
Impact of ozonation on subsequent treatment of
azo dye solutions.
Besides acting as an auxiliary agglutinating polyelectrolyte, chitin and chitosan are good adsorbents capable of removing
azo dyes efficiently from textile effluents (DUARTE et al.
According to reports, certain types of
azo dyes can break down to form "aromatic amines" when there is prolonged contact with the skin.
