However, during post-treatment of anaerobically treated azo dye containing wastewater, there will be competition between biodegradation and autoxidation of aromatic amines. This may be problematic not only because the formed products are colored but also because some of these compounds, e.g., azoxy compounds, may cause toxicity.

Reactive Dye - an overview | ScienceDirect Topics
Reactive Dye - an overview | ScienceDirect Topics

Reactive dyes form a new chemical compound when they come into contact with a fiber molecule. Reactive dyes are applied either from a solution with high pH or from neutral solutions that are later alkalized through a separate process. Sometimes different shades are brought out by applying heat to the dyed textile. Originally, reactive dyes were applied to cellulosic fibers but today other ...
