Azo‐Dye Rotaxanes

Angewandte Chemie International Edition in English, 1997
The hydrophobic effect was used to assemble encapsulated azo dyes such as 1 in water. The dumbbell-shaped dyes were synthesized inside α-cyclodextrin, β-cyclodextrin, or a cyclophane to yield stable rotaxanes.

Potential use of bacteria collected from human hands for textile dye decolorization

Water Resources and Industry, 2018
We obtained dye-decolorizing bacteria from the hands of ordinary people with an efficiency of approximately 40%. The bacteria were classified into the azo dye-decolorizing group and anthraquinone dye-decolorizing group.

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 ...
