Decolorization and degradation of reactive dye during the dyed cotton fabric rinsing process.

Dyeing process of textile consumes large quantities of water, which results in huge amounts of colored wastewater. Most of the dye wastewater treating methods focused on the treatment of wastewater after the rinsing process of dyed textile. In this paper, tetraacetylethylenediamine/hydrogen peroxide (TAED/H₂O₂) active oxidation (AO) system was developed to rinse dyed textile and decolorize the rinsing wastewater simultaneously.
