Removing Reactive Dyes from Textile Effluent Using Banana Fibre

Reactive dyes are highly preferred for cotton for their excellent fastness properties and easy application. But problem in reactive dyeing is the low exhaustion properties due to the hydrolysis of reactive dyes with water. This method consumes only a small amount of water and energy. Removal Reactive Dyes are related to Water of Dyeing Production.

DYE WASTEWATER TREATMENT: REMOVAL OF REACTIVE DYES USING

Discussion. Reactive dyes usually have more number of functional groups such as azo (N=N), sulfonic acid (- SO3-), hydroxyl (-OH) etc. Thus, these dyes are more stable apparently due to charge distribution, which could be one reason why reactive dyes are more difficult to remove using conventional coagulation.
