What is Reactive Red 31 (RR31) and why is its degradation in wastewater a significant concern?

Label:chem

Topic
Compound: Reactive Red 31 (RR31)
Answer
Reactive Red 31 (RR31) is a synthetic dye with the chemical formula C30H15ClN7Na5O15S4 and a molecular weight of 992.14. The complex aromatic structures of dyes like RR31 make them persistent in wastewater. Large quantities of heavily colored wastewater containing synthetic dyes are discharged from textile and similar industries, posing a significant treatment challenge. Furthermore, some dyes are either toxic or carcinogenic , and traditional biological treatments are often insufficient for complete color removal from effluents.
